 The display contrast is nice and the sunlight legibility is the best we have seen on a Sony Ericsson handset. In fact out there in the bright sun, the Sony Ericsson XPERIA X10 is as good as the Apple iPhone. 

All the homescreens, lockscreen, menus, submenus, notifications areas and internal buttons have been redesign completely by Sony Ericsson. As a result, X10 brings a completely new underwater-like blue interface and looks completely different from it Android siblings.
Sony Ericsson XPERIA X10 takes pretty good photos with excellent detail and colors even at this early pre-production stage. There are no visible problems with the lens or processing algorithm. There are some things here and there that need polishing, but we are more than satisfied with the results.

Sony Ericsson XPERIA X10 is far from official release but it's clear it's full of potential. It has among the currently fastest ticking hardware platform. The 4-inch screen is as big as you can fit on a mobile phone without hampering usability. So yes, the XPERIA X10 is one great package that will take on the competition with no hesitation.
Choosing Android is smart move by Sony Ericsson, since the OS is still new and developing, with free open-source code and a growing App Market. And most importantly, it's not plagued by the Windows Mobile or Symbian legacy.

The Timescape and Mediascape interfaces allow for a completely new user experience on the Android platform. HTC Sense UI will definitely get a run for its money.
Unfortunately, there are at least two and a half months to go before Sony Ericsson release the XPERIA X10 and they still have a lot of work to do and a lot of edges to polish. Chances are we'll be getting a real treat in February 2010.
