It seems you guys have missed out the 3D GPU in your spec list! Any idea what it is?
Coz it says "all vividly displayed as photos and artwork powered by the 3D graphics processor." here:

My first thoughts on the new UI is its just another HTC gimmick you probably will turn off so you can have access to the hundreds of home screen plugins available. If HTC want to improve the WM UI they need to open up their API for the controls they use in their fancy home screen so devs can use them in other apps. WM's biggest problem is lack of consistency across apps, especially when you are using your finger to launch an app then have to wip out the stylus to click on tiny menus in Pocket IE. As long as we have this consistency problem there is no chance of competing with the iPhone.
