Ever since Netbooks appeared throughout every computer store, I fell in love with the idea. I've had a laptop (Acer) for two years now and I always thought it was not portable at all, because it is oversized and overweight: difficult to carry around.
Although it was difficult to make up my mind regarding which model or brand I would choose, I found that this Acer Aspire One A150 was both cheap and light; aswell, it has a very satisfactory storage hard disk and has just about what it takes to be a perfect supplement and helper for my college classes and future profession.
I used to carry over 20 lbs over my back, counting books, notebooks and every other extras, and everyday I felt that some other thing should have fitted in my backpack. Today, I carry all my books and notebooks around, along with all the extras I need, packed into a marvellous 10lbs suitcase :)
I love it!

The first thing you notice is that this is not a small lightweight camera, but is a solid well built camera designed for serious use, yet despite it's size and weight it is still easy to hold and is comfortable to use, for those of you that have used the EOS 40D it has the same body shell as that, and has the advantage of using the same accessories as the EOS 40D as well.
The menu's are well laid out and easy to use making this camera easy to set up and use, the large LCD screen is bright and clear, and much higher resolution than previous EOS cameras,(920,000 pixels) excellent for manual focusing in live view and checking the focus of pictures you have already taken.

Auto focus is lightning quick and accurate under normal conditions, and even in low light conditions it is still quick. (tested with canon lenses)
Cramming 15 megapixels resolution onto a small sensor causes problems with digital noise on many cameras, but not here, digital noise (graininess) is not apparent at all until you get into the highest ISO settings (ISO-100 to 3200 is available) and even then it is well controlled, (there is also the option of setting a very high ISO-6400 or ISO-12800 setting but noise is apparent at such high settings and is best used in emergency only,) with it's 15mp resolution, even severely cropped or greatly enlarged pictures are crystal clear, (see example pictures below for details) colours are rendered accurately, even in difficult lighting conditions, when set to auto white balance, snow comes out as white snow, not bluish as on some other cameras that I have used, picture quality really is superb, and has to be seen to be believed.

One thing I have noticed, is that this camera, when it is set to program mode, has a tendancy to slightly over expose pictures under certain lighting conditions, especially Where if there is water or any other reflective surfaces present, I usually set. the camera to auto-exposure bracketing by either a 1/3 or a 2/3 of a stop to compensate for this when taking these pictures, but as it is usually less than 1 stop over exposed it is fairly easy to fix this in post processing, this is where RAW files (digital negatives) come in useful as they contain more picture information than jpegs, so over and under exposed areas can be fixed a lot easier, the camera comes supplied with very good RAW editing software, but I normally use photoshop to edit my RAW files as that is the software I am more used to using for this, you get the best of both worlds with this camera as you can record both jpeg + RAW files simultaneously. (RAW files are the raw data that a camera records and must be converted after processing to a useable picture format, such as jpeg, bmp, gif, tiff etc. that can be displayed on a PC or Mac screen, and used for printing.)
Example of picture quality even when severely cropped and enlarged

Picture 1
The clover picture above was cropped from a small portion of the full image, (approx. 10% of the original).
Picture 2
The river picture is a full uncropped frame (reduced in size to 1500 pixels wide to fall within Ciao's picture and file size guidelines), It was deliberately taken in adverse lighting conditions (just before sunset) to show up any faults such as High ISO noise

Picture 3
Is a small area of picture 2 cropped down to the railings. this area was deliberatey chosen as it is a darker & lower contrast area which will show up more noise in the picture than would a bright & high contrast area.

Notice the lack of any appreciable noise and pixellation. even at this level of cropping, fine detail is still rendered accurately (click on images 1 & 3 then select XXL view to see the fine detail of cropped images) no post processing other than cropping and resizing was applied. (more pictures will be added in due course)
Other feartures

The built in flash is adequate for most situations but if you take a lot of flash photos and need a higher output flash, then one of canon's speedlight flashes can be used instead.
It is compatible with all Canon's EX series speelight flashguns.

It has a fast 6.3 frames per second high speed continuous shooting mode,
and a 3 frames per second low speed continuous shooting mode.
It is compatible with the latest high speed, high capacity CF cards, making it possible to fit thoudands of pictures onto one card, even when shooting jpeg + RAW simultaneously at maximum resolution. I have a 32gb 133x CF card in mine and I can fit a whole days shooting onto it, and still have plenty of room to spare.

It is compatible with all canon EF and EFS lenses, and with canon's image stabilised lenses you get pin sharp pictures even in low light or with longer telephoto lenses. * (see notes below about chosing lenses for this camera.)
PRO's
Good all round performance.
Excellent picture quality.
High resolution with low noise.
Good low light performance.
Quick and accurate focusing and a very effective image stabilisation (with Canon's IS lenses)
Live view function.
6.3 frames per second continuous shooting.
Well built and strong with its metal body shell.
Takes the same accessories as the EOS 40D
Compatible with the latest high capacity CF cards.
Raw or Jpeg files are recorded, Raw+Jpeg simultaneous recording is also possible.

CON's
large and heavy.
No movie function.
No CF card supplied, so if you don't already have one, you will need to buy one before you can use it (with 15mp resolution the higher the capacity of the card the better).

In conclusion
This is an excellent camera for the serious photographer and is a worthwhile upgrade from an older camera.
If you already own an EOS 40D then the difference in performance would not warrant the expense of an upgrade, but if you want a second body with higher resolution then this would be an ideal companion to your existing EOS 40D, as most of the functions are the same and you can use all your current accessories with it.
It would also be a good back up camera for a professional photographer, who does not want to go to the expense of a second full frame pro camera.

It is more expensive than some other "prosumer" cameras, but with the features and performance that you get, it is worth every penny.
Highly recommended.

* Notes and advice on choosing lenses for this camera.

There is often confusion for people when buying lenses for DSLR cameras (especially if they are new to DSLR's), as the actual focal length of a lens is not the same as the effective focal length that they will get on their camera, and most good camera shops have conversion charts to make this easier when advising their customers of the best lens to buy for their needs, but most online shops do not, hence the advice below.
Here's why

When you buy a lens it has a stated (actual) focal length, or range of focal lengths in the case of zoom lenses, (magnification) measured in millimeters, e.g. 100mm focal length.
The stated focal length on any lens is rated for 35mm film cameras and professional full frame DSLR cameras with a censor size of 35mm x 24mm, this is the standard rating for all SLR lenses.

The censor on this camera (and on most EOS DSLR cameras) is the "APS-C" sized censor with a measurement of 22.3mm x 14.9mm, this means that the effective focal length of the lens will be different to the stated (actual) focal length of any lens you buy when used with these cameras, this effective focal length is known as the "35mm equivalent."
This is not a fault, but is a feature of all DSLR cameras, with the exception of professional full frame cameras.

To find the 35mm equivalent of any lens used, you must multiply the stated focal length of the lens, by a factor of 1.6, thus a 100mm lens will have an effective focal length of 160mm (35mm equivalent) when used with these cameras.
This is great news if you want to use telephoto lenses for wildlife etc. as you will get higher magnification from your lens, for less cost than on a full frame camera, so a 70 - 300mm zoom lens will have a 35mm equivalent of a 112 - 480mm zoom lens.

But on the other end of the scale, wide angle lenses will be less wide, and you will need to buy a more expensive wider angle lens to compensate for the difference in focal length, thus a 10 - 22mm ultra-wide angle zoom will become a very useful 16 - 35.2mm wide angle zoom.
The standard lens on a 35mm camera is 50mm which gives approx x1 magnification, but on these cameras, it is the equivalent of an 80mm portrait lens, 31.25mm would give you the equivalent of a 50mm lens (35mm equivalent) on these cameras.

The coversion factor for Canon cameras is x1.6 of the stated focal length, other camera manufacturers may vary, so it is best to check the manual of your camera first.
So if you are new to DSLR cameras, or are upgrading from a 35mm film camera, I hope this info will help you to make the right choice when buying extra lenses for your DSLR camera, because the difference between the actual and effective focal length of a lens can significantly change the type of photo which you can use it for.

The MacBook Air is driving me insane. I want it like no other hardware. It's thin, yea, ok, we know this. And many power users have been bitching for more: 3G, bigger storage, more USB ports, and an internal drive. If you feel that way, this computer isn't for you. I'll go ahead and call it the most simple, focused, and beautiful laptop ever. And the MacBook Air's shortcomings matter no more than the discomfort that fashionistas endure while wearing high heels, or car fanatics do when they have to fill up their tanks twice a week in their 5MPG sports cars. It just doesn't matter to those who are smitten. For the rest of you, here are the facts.The Basic Guts:
The Air has a Core 2 Duo chip in a specially designed package and small motherboard that help reduce its thickness. The LCD screen is backlit with LEDs, which saves battery, and allows the screen to be dimmed much lower than CCFL screens for additional battery. It has Wireless N/B/G, Bluetooth 2.1 EDR, and is available in two basic configurations: $1799 for a 1.6GHz chip, plus 2GB of RAM and a 80GBs 4200 RPM Drive. For almost double the price at $3098, you can get a 1.8GHz chip with the same 2GB of RAM and a 64GB solid state drive module that, like all SSD, is shock resistant. There is no ethernet port, only a USB to ethernet jack that needs to be bought separately. And there is no optical drive, save the $99 optional external. For all the bitching we do about it not having 3G cellular data, Apple considered it but couldn't fit it into the case and didn't want to lock consumers into one carrier.

The Hardware Details:
The Air has a few notable hardware elements all paying homage to the original conceit of a stripped down laptop. It has one USB port, a headphone jack, and an external monitor port, all tucked away in a fold down compartment. The USB port is difficult to get to, and keeps fatter USB devices from mounting. There's no firewire, so no target mode. Above the keyboard and screen, there's an iSight camera for video conferencing and stills, which records to 640 by 480 res (same as other iSights). Next to each are laser cut grills. One is a light sensor which adjusts the keyboard backlight. The other is the microphone. The Air has a single speaker, but its much louder than the speakers on the MacBook (But not those on the MacBook Pro.) Oddly enough, it's built under the arrow keys on the keyboard. The touchpad we'll address later. BTW, even the insides are beautiful (yes, we already opened it) reminding me of the Fake Steve Jobs rant about the iPhone's CPU not being perfectly centered. Fake Steve would not be able to complain about these guts. Build quality is excellent. The general twisting you get in the frames of most laptops is practically gone. One minor quirk. The right side of my screen is not flush with the main chassis when the lid is closed. The cooling system is adequate. Using it on your lap is perfectly acceptable, temperature wise. Oh one more thing about thinness: While using the Air, you never feel that edge of the front wrist rest because it is so narrow. Very, very nice.

Performance:
It's the slowest Mac you can buy right now. But our benchmarks show it to be sufficiently fast, and between the performance of a last generation MacBook and MacBook Pro (machines people likely have.) We tested the 1.6GHz 80GB MacBook Air and several things were clear: The CPU was adequate, the 2GB of standard config RAM helped with multitasking and big file handling, and the 4200 RPM drive was a bit of a bottleneck, especially compared to the aftermarket drives in the older machines. We look forward to testing the SSD version of the laptop. More performance details here in our benchmark post.
Portability:
It's thin to the tune of 0.16-inches at its thinnest and 0.76-inches at its thickest. OK, you've been beat over the head with that, and with many sizemodos. But does thinness make it portable? I'm not sure. The thicker but smaller Sony TZ and Apple's old 12-inch powerbook seem more portable, simply because they can fit into bags that are smaller than backpacks. And is it useful as a road machine? I think the Sony TZ is a better professional road rig, for all its storage, battery life of almost 10 hours, and 3G data connection. But I think the Air is a much easier machine to work on, thanks to its fuller sized interface and LCD, and is more appropriate for trips to the library or sitting on the couch because of how sturdy it feels being carried in one hand. In this way, it is perfectly spec'd for the majority of the world. (Sorry power users. Few consumers are going to spring 70 a month for 3G, as cool as it is.) The rest of us can lug a USB hub, someone will come out with an external magsafe battery pack, jack in a USB 3G data modem, and turn the Air into a monstrosity. You could also get a MacBook Pro. The Air is a focused machine that does the basics in a form factor that fits in with sheets of paper, magazines, and other stuff you'd toss into a backpack. It works.

New Magsafe:
The 90 degree bend is much nicer than the old version, which always wore quickly near the seam. That bend does make it a little harder to snap into place, since the magsafe is under the Air. Oh, one note: Your old Magsafe adapters fit, but the plug is a bit too big and when you rest the Air on a table, it knocks it off.
Multitouch:
The version of Leopard that ships with the Air supports iPhone like multitouch on that big ol trackpad. It's almost 5 inches diagonal vs about 4-inches on other Apple notebooks, but the touchpad bar is thinner than usual and takes a minute to get used. It supports basic two finger scrolling like in the current Mac laptops, but adds interesting features:

•Rotating two fingers in iPhoto or Preview rotates the image.
•Three finger swipes up and down or side to side work much like a next or previous arrow keys, switching between images in photo programs, web pages in safari, days in iCal.
•The iPhone's Zoom in and out using pinch and spread gestures works too. In Safari, it increases/decreases the font size.
•Multitouch support is not generic. In Firefox, all the tweaks in Safari do not work.
•We tried to install the Air's version of Leopard onto a MacBook to see if we could get multitouch activated on an older machine. Predictably, no dice; the disc wouldn't install on a non Air machine.
Multitouch is not nearly as effective on the touchpad as it is on the LCD of an iPhone. That is partially because the iPhone's UI and screen are one, but its also the texture of the touchpad vs the glass on the handset. It just doesn't feel as smooth.

Remote Disc vs the External Superdrive:
Apple's Remote Disc allows the optical-less Air to borrow a networked computer's optical drive. comes on the install disc, and is a hefty install, and it includes PC and Mac versions. Remote drive doesn't support a lot of multimedia playback over the network: It can't rip CDs or DVDs by iTunes or Handbrake, doesn't support even basic playback. It's functional for installing programs, but not versions of windows that need to be installed from bootcamp. Plus, every time you use the remote drive, you have to get permission via a prompt on the non-Air machine's screen. Very Vista like. For these reasons, I recommend anyone who gets an Air to get the accompanying superdrive, not only for the road, but for the tons of critical things you can't do without it at home. It reads CDs at 24x, burns CDs at 24x, burns DVDs at 8x, and Double Layer DVDs at 4x. (It does not, however, work with other Macs.)
Keyboard and Screen:
Apple's full Keyboard and LCD Screen give the Air a footprint larger than that of the competition. Counterintuitive, but it works. That nagging feeling you get when you have to tuck into a few hours of work into a subnote's tiny interfaces are gone, so I'd have no hesitation using the Air for 8 hours a day. The keyboard is backlit, and black, perhaps as a homage to the titanium notebooks from Apple a few generations back. (And will be useful in keeping the keys from looking disgusting after a few months.) The spacing is the same as that on the standard MacBook, which I like, it has arrows and the updated dashboard, expose, and spaces buttons on top. The keyboard is also backlit, and uses the ambient light sensor to change its brightness.

The battery ain't that bad:
The 34 watt internal battery of the Air has been a point of contention for pros who do lots of field work. That's fair, considering this is a highly portable machine. You shouldn't worry. We took that mother apart and found it was far easier to deconstruct than any notebook Apple's ever made. With a small philips head screwdriver, the thing takes 5 minutes to disassemble. And the battery was simple to swap, no glue, just a few screws. I even think the aftermarket can make a new aluminum base that allows for battery swaps. I'll update this post with battery life info very soon, but a preliminary test shows that it's slightly lower in capacity than what Apple's 5 hour rating. (No surprise.) We'll see if using 3G on this smallish battery (fine for the low power system itself) go to mush with serious use. UPDATE: The first rundown test included putting the Macbook Air on normal power settings, prohibiting the screen, computer and drives from going into power save mode. Then we ran mp3s through the speakers using iTunes. We're at 3:15 and its just about done. More rundowns tomorrow. UPDATE: A second day of battery testing shows the Air lasting 4:30 by lowering LED brightness from full to midpoint. An alarming find is that the 45watt Magsafe adapter (an ipod adapter sized brick) will charge the Air from empty to full in 8:30 with the Air in sleep mode. We've confirmed this twice. Will test with a Macbook Pro adapter to see if that changes anything. (I doubt it, but we'll see.) UPDATE: Phew. Retests show the Macbook Air charges to full battery in about 3 hours with either charger.
Value:
It's hard to put a price on such a thin, simple and interesting machine. The $1799 MacBook Air with a 1.6GHz, 2GB of RAM, and 80GB of space is not a deal, but this is the lightest OS X machine out there. $3098 for the 64GB of SSD and a relatively meaningless bump to 1.8GHz is ridiculous. If this is a secondary machine, you shouldn't pay more for this than a more powerful and capable MacBook Pro. For comparison, some SSD laptops include 128GB of storage for $3k.

How it fits into your life:
As a pro writer, I'd never be able to depend on this machine for every day use. (In the field, I carry half a dozen batteries and backup 3G modems.) This machine's mainstream appeal shouldn't be underestimated. Some might call it the iPod of computing. It'll never be my primary, that's obvious. And while I usually use my old machines as secondaries, I find myself every day more and more unable to resist buying one of these first, and figuring out where it fits into my life second. I've just never been that rational of a person, and I'm fine with that

Apple have taken a completely new direction with the 'touch', and boy has it worked. Using the same technology found in the iPhone, scrolling has never been easier - you won't miss your click wheel at all!
Boasting a gorgeous large colour screen, watching video on the move has never been this good. The music still sounds as good as ever, however the supplied apple earphones to leave to a bit to be desired. This problem can however be overcome with a simple upgrade of the earphones, allowing you to use your device to it's full potential.

One new feature this iPod brings is it's wifi connectivity. Although I was rather sceptical at first, surfing the web on this is a breeze. Apple really have tried their best to make touch screen web browsing an easy to use simple feature, and in my opinion they have done a very good job. Although there is no support for flash, web browsing on the iPod touch is a very enjoyable experience and after a while you will find that you use your personal computers less and less for surfing the web and checking email.
Another big advantage to the touch is the addition of apple firmware 2.0, which allows applications to be stored onto your device through the itunes store. Many of these are actually free, and prove that the iPod touch is far, FAR more then a simple music player. I recommend you buy one now

Windows Vista is one member in a family of operating systems developed by Microsoft for use on personal computers, including home and business desktops, laptops, Tablet PCs, and media center PCs. Prior to its announcement on July 22, 2005, Windows Vista was known by its codename "Longhorn."Development was completed on November 8, 2006; over the following three months it was released in stages to computer hardware and software manufacturers, business customers, and retail channels. On January 30, 2007, it was released worldwide, and was made available for purchase and download from Microsoft's website.The release of Windows Vista came more than five years after the introduction of its predecessor, Windows XP, the longest time span between successive releases of Microsoft Windows desktop operating systems.

Windows Vista contains many changes and new features, including an updated graphical user interface and visual style dubbed Windows Aero, improved searching features, new multimedia creation tools such as Windows DVD Maker, and redesigned networking, audio, print, and display sub-systems. Vista also aims to increase the level of communication between machines on a home network, using peer-to-peer technology to simplify sharing files and digital media between computers and devices. Windows Vista includes version 3.0 of the .NET Framework, which aims to make it significantly easier for software developers to write applications than with the traditional Windows API.

Microsoft's primary stated objective with Windows Vista, however, has been to improve the state of security in the Windows operating system. One common criticism of Windows XP and its predecessors has been their commonly exploited security vulnerabilities and overall susceptibility to malware, viruses and buffer overflows. In light of this, Microsoft chairman Bill Gates announced in early 2002 a company-wide "Trustworthy Computing initiative" which aims to incorporate security work into every aspect of software development at the company. Microsoft stated that it prioritized improving the security of Windows XP and Windows Server 2003 above finishing Windows Vista, thus delaying its completion.
While these new features and security improvements have garnered positive reviews, Vista has also been the target of much criticism and negative press. Criticism of Windows Vista has targeted its high system requirements, its more restrictive licensing terms, the inclusion of a number of new digital rights management technologies aimed at restricting the copying of protected digital media, lack of compatibility with some pre-Vista hardware and software, and the number of authorization prompts for User Account Control. As a result of these and other issues, Windows Vista had seen adoption and satisfaction rates lower than Windows XP. However, as of January 2009, it has been announced that Vista usage had surpassed Microsoft’s pre-launch two-year-out expectations of achieving 200 million users by an estimated 150 million.

'm not ashamed to say it... i'm addicted to digital cameras. Now, as a photographer / designer, this may sound like a fairly innocent claim, but it can be rather costly - especially as my latest purchase was the $1200 Nikon D90 12.3 Megapixel SLR.
'SLR' (single lens reflex) cameras have interchangeable lenses and a larger image sensor than found in your common-or-garden compact. This results in a better image quality and a huge variety of customisable options. Of course, this also means that they are more expensive than their smaller and more user friendly siblings - but you generally get what you pay for.

The D90 represents Nikon's intermediate option, with the cheaper D60 being the entry level model, and the top-of-the-range D3 aimed at serious (and rich!) pro's only.
The D90 has been designed so that it is easy enough for a new digital SLR user to use, whilst having enough advanced options to please seasoned photographers.

In terms of its design, the D90 looks a lot like its predecessor the 'D80' which was released a couple of years back. Apart from its slightly cleaner lines, the first obvious change is the huge three inch LCD screen on the back, which makes viewing your photos a pleasure.
Internally, the D90 has a set of impressive features including 4.5 frames a second continuous shooting, and a dust reduction system which cleverly prevents dirt and other tiny bits of debris finding their way onto the image sensor when changing lenses.

However, the reason that this particular camera has been grabbing all the headlines recently, is due to its ability to shoot high-definition video. Now, this may not sound like much - all cameras have movie modes right?... well, actually, wrong - the Nikon D90 is the first SLR to have this feature. The camera can record at 1,280 x 720 pixels, at 24 frames-per-second with mono sound. The downside to this is that focussing during movies has to be done manually, as auto focus is disabled whilst recording. The addition of the movie mode is a nice bonus, but overall it is a feature which I probably will not use.
As I mentioned in the first paragraph, the D90 offers 12.3 megapixels of shooting power - but megapixels often get confused with image quality, and have little to do with a cameras overall performance.

So how good are the pictures which the D90 can take?
My first impressions of the D90's image quality were outstanding - The colours that this camera produces are incredibly accurate and there is a great detail in both the shadowed and highlighted areas of my images.

Overall, I found some shots to be a little soft - but this isn't a huge problem, as the sharpness levels can be adjusted as part of the in-camera settings. I found that changing the sharpness from the default value of '2' up to '5' addresses the problem, and will produce better shots in the long run.
In terms of the image grain, or 'noise' as it is referred to in digital camera terms, the D90 does a good job in most circumstances. Offering an ISO range of 200 - 3200, noise is only noticeably introduced at around ISO 1200. For those of you who are unaware of what 'ISO' means, basically it represents the sensitivity of a cameras sensor. Using a higher ISO number will allow the camera to take pictures in lower light, but the result will be more noise in the final picture.

White Balance is excellent, and a novice user can happily set the D90 to 'auto' and let the advanced image processor do the dirty work for you. If you want to tinker yourself however, adjusting the white-balance (or any other setting on the camera for that matter), is really easy, and can be done via the well designed menu system.
Nikon SLR cameras generally have a great auto-focus system, and it is the same with this model. There are a range of options including face detection and 3D tracking modes, and the D90 is quick to lock-on to subjects, which makes composing your images a breeze.

The build quality of the Nikon D90 is excellent. It feels more substantial than my previous camera (the D60), and there is a noticeable increase in weight. That said, it isn't too heavy to hold, and feels like it would happily survive the odd knock or low drop (although i'm not going to test that out!). Overall, it is comfortable to hold and as long as you have a fairly light lens attached, will not make your arms too tired.
Below is a summary of the Nikon D90's extensive features:

In conclusion, Nikon has designed the D90 for both beginner and advanced SLR users, and it is instantly obvious to me that they have succeeded. The menu systems are clean and easy to navigate, whilst there are a range of options hidden away which will allow endless tinkering for the pro users who want a greater level of customisation.

Most importantly, the D90 is a fun camera, and although it sounds expensive, it offers great value for money when you consider firstly the build quality, and secondly the stunning images that it is capable of producing. The movie mode is an added bonus, but will no doubt appeal to users who are interested in producing creative digital video as well as high quality stills.
I highly recommended the D90 as a stunning piece of photographic equipment, Nikon have yet again designed a formidable machine - did I mention that it has a 0.15 second start up time? - that's also impressive!

I've also posted this review on dooyoo.co.uk under the same name.

Me and My friend both owned a T - Mobile and it has very good features with many advantages , this internet smart phone has excellent quality with best features . it is available in Black , Red and green in color . light weight with strong battery will add a additional plus point to it .the major effective disadvantage which i found in this smart phone is just software problems it has a strong Android Operating System with it but though some times some files cannot excess in time and that makes me so irritative .

# Display :
It has high resolution TFT - LCD Screen with 480 X 320 pixel resolution . this quite stylish touchscreen makes work more reliable and easy in all the manners , this smart phone has half sized VGA screen which will give you a better clarity and the best performance . it has good touch screen , normally I phone , I pod or Apple Inc has this kind of amazing screen .

This mobile phone contains a keyboard as well (This phone is equal to a personal computer / laptop) .

This sliding qwerty keyboard is very easy to use and very comfortable like normal personal keyboards .

# Camera :
Good effective and strong Camera you will have with this T - Smart phone . this G1 has 3.2 mega pixel camera with 3GPP Faciltiy , i found a normal disadvantage is this camera doesn't have flash light as a result very poor in low light or in dark nights .

Design of slidding bar is not a new thing on Pdaphone.
The form of the body visible sag when the body has opened up a Sony Ericsson bid. When we push the body up to the right will be visible to the existence of the Qwerty keyboard.

This keyboard consists of four lines. The distance between each key is quite thin, so we will not click through the error. To pass up the phone, we can simply press the button-key number, no need to press the button to change the function first.


We only find the Windows key in the key first, and the OK button on the key line to the last four. Not visible in the button row keyboard shortcuts, as well as with the two menu buttons that are usually placed between the keyboard and the screen body. The OK button for the other can be found under the right side of the screen.

Another innovation from Sony Ericsson is the panel, which became the theme as well as the application menu. To access the settings panel is very easy, because the X button penempatkan Panel under the screen to the left. We live panel squeeze the desired, and the panel will be activated immediately.


Touch screen is very vulnerable, therefore anticipated that with the key one is made with the End call button. We live click and hold the button End call to Unlock any posts appear. To Stylusnya we can find on the left side of the body.

Connectivity / Capacity / Performance =
Mini USB port which is located on the left side of the body used for the charger / data cable. I had difficulty looking for Micro SD slot that is located on the left side of body. Micro SD This is not visible because the casing is made from behind the metal. To be able to open the casing with a small poke holes in the right and left on the bottom of the body. The Sony Ericsson provide MicroSDHC 4GB Sandisk brand into the package.


The combination of processor and memory is selected by Sony Ericsson seem to match the operating system used. At least we see a graphical display on the X panel that flows beautifully.

Entertainment =
Xperia X1 is equipped with a camera "3.2" MP, added lights. I do not find the Camera icon in the menu, it seems this application can only be opened by pressing the camera key, which is located right in the bottom of the body. Picture size images can be obtained only up to 3MP. Video and size for the video recording is VGA.


Additional speakers almost not visible, located on the left side of the lower part of the body. The volume key located on the right side of the top of the body. Of particular interest is the jack Xperia X1 "3.5" mm to the headset is in the top of the body.

Just be that Google and the FM Radio does not see its icon again in the Programs menu and setting. This application can only be accessed from the X Panel. We hear that the information Sony Ericsson will add a new panel to access Facebook and Windows Live Messenger is distributed by Dashwire.


Xperia X1 also provide facilities that GPS accuracy disa reliable. However, this facility is Battery drain energy. Besides there are also QuickGPS and Google Maps. If we want a more detailed map, we have to buy yourself a map to a third party.

Although new players in making peranti-based Windows Mobile, but Sony Ericsson strives to provide the best for us. See the price being offered, some of us may have to drain the wallet to be able to get it.
