You can get a pretty good preview of the Sony Ericsson XPERIA X1 over at Smape. Along with comparisons to the HTC Touch Pro, you can also get a look at several images of the Windows Mobile device and its accompanying specs.
 

The X1 will launch the XPERIA product line of PDA models, which is an ODM-produced by HTC that has a keyboard. This device is set to be rather different than previous WM models. For instance, it will contain metal on the front and back panels, is lightweight and has a chrome coating.

The pros and cons of the X1 were also outlined as follows:

+ Stylish design, original form factor
+ High quality of materials and assembly
+ Large high-definition screen
+ Long battery life
+ 3.5 mm audio jack
+ XPERIA panels firmware launcher
+ Powerful CPU, 256 Mb of RAM
+ Wi-Fi and GPS, as well as an FM tuner
- High price
- Challengeable keyboard ergonomics
- Non-canon screen resolution
- No TV-out
- No hardware 3D acceleration
