The Sony Ericsson Xperia X10 might just be the most anticipated Android-based phone since the arrival of the Motorola Droid.

The X10 promises to be one of the most powerful Android smartphone on the market thanks to tha 1GHz Snapdragon processor, 8 Gb of included storage,an 8.1 mpx camera and Sony’s Nexus UX platform.

It has a huge WVGA touchscreen, but despite that it’s pretty small.This smartphone is almost the same size as the original iPhone and easily fits into your palm or hand.

The software really makes this phone so special.

The Nexus UX platform sits on top of the Android operating system on the X10.
Nexus adds “signature applications”, a newer and richer GUI, and lastly improved service integration so your Twitter account, e-mail accounts, media player and more all work together seamlessly.
The Nexus UX platform lets you easily jump from a friend’s Twitter or Facebook account and email them in a matter of seconds.

Timescape is the first “signature app” for the Nexus UX platform, which helps you organize photos,email,SMS,Twitter and Facebook.

The Xperia X10 also offers face recognition software built into the Nexus UX platform so that if you take a photo of someone and “tag” their face with their name, the device will automatically recognize that person and organize the photos with your contacts.
This means that if you press the person’s face again the X10 will automatically bring up that person’s contact info, Twitter, Facebook, and any other photos of that person.

Sony Ericsson has just announced the price of the X10 in the UK at approximately $879, but it’s too early to say whether this pricing reflects the actual “street price” of the X10 from U.S. carriers.
