The live wallpapers are pretty fucking cool. I wish we could use our own videos as background though...

The 3d gallery is pretty stupid, I mean, so what I can sort of 'tilt' the pictures? Lame. I was able to upload to Picasa though which was pretty cool (Im not sure if I could do that before). However, picture navigation is much sleeker and has pinch-zoom which seems to follow the iPhones design (which isn't a bad thing imo).

The 2.1 version is A LOT slower than previous versions everything just runs... slower...

Lastly the pinch zoom is pretty nasty for the regular browser. But I think xScope may be slightly faster...
