Engadget was able to play with a pre-release version of the Sony Ericsson Xperia X10...

Sony Ericsson XPERIA X10 announced, we go hands-on

Unlike the X1 and X2 Windows Mobile based models, the X10 is based on Google Android and is Sony Ericsson's first Android phone. And, unlike the X1 and X2, the X10 is yet another keyboardless iPhone copy cat.

The X10 does have a its distinquishing features though:

- 8.1 megapixel digital camera (um, wow!)
- Custom Android skin codenamed "Rachael" (I wonder if it has its own SDK like the X1/X2 Panels UI?)
- Sony Ericsson developed Timescape social network app (see video embedded above)

For me, however, without a physical keyboard, it is a non-starter. I'm sure it will have appeal to many people. But, unless Sony Ericsson can cut a deal with a major U.S. cellphone carrier, don't expect to see it in this country in 2010.
