The Sony Ericsson XPERIA X10 (that's what it's called now) has been officially unveiled and the details are now clear for this most anticipated device. Everything we saw leaked and loved is there--Android, 1GHz Snapdragon processor, 4-inch touchscreen, 8.1 megapixel camera, and of course, the 'Rachael' UI. Everything about the hardware is still the same--beautiful lines, slight curves, and an overall stunning design. So what's the news?

Sony Ericsson is planning a whole line of these 'Rachael'-powered devices with the XPERIA X10 being the flagship device. The 'Rachael' UI might even pop up on other operating systems like Symbian and maybe even WinMob. All of these 'Rachael'-powered devices will likely show up in the first half of 2010 (so DROID, you have nothing to worry about...yet)

Sony Ericsson added their own touch to Android 1.6 and we're really impressed with some of their concepts. They're introducing Timescape, a MOTOBLUR-esque social networking integration that streamlines all of your social networks. Mediascape, which is the beautiful music application we saw yesterday. And face recognition, which will allow for automated photo tagging by recognizing your friends after they've been tagged by you and will even allow you to call friends when you tap on their face when viewing a picture (not entirely useful but amazingly cool nonetheless). Can we agree that this sounds amazing?

The only problem is that in its current stage, 'Rachael' seems to be more proof-of-concept than actually being ready for the primetime. Engadget had the opportunity to play with a pre-production X10 with a very early build of the 'Rachael' UI and simply couldn't get a real feel for the software (it's that far from being finished). But regardless, Sony Ericsson is taking a gigantic step in the right direction and could very well re-define how smart our smartphones can get.

Though we admit we wanted to hear an official release date, price, and carrier for the Sony Ericsson XPERIA X10 today, we're still satisfied with what Sony Ericsson has done. If they deliver on their promises, we're certain that it'll be 'extraordinary and magical'.

What do you guys think?
