Well this certainly caught us at Berble by surprise, Sony Ericsson have announced a Windows Mobile handset, an impressive looking piece of hardware it is too.

All of Sony Ericsson's current handsets use UIQ, which runs on top of Symbian OS so the move to Windows Mobile is unexpected.

The stand out features of the X1 include a 800x480 3" touch screen and a slide out curved querty keyboard.  Check out the photos and video after the jump...

Autofocus 3.2 megapixel camera, Bluetooth™ stereo (A2DP), FM radio, GPS, Wifi, microSD card slot all get name checked and reading through the specification list it's hard to spot anything missing.

Arguably it has the looks to compare favourably with the iPhone too.
