Hmm.. I thought I posted this stuff last night. Maybe I did but not here.
Anyway the claimed standby times are longer even with the smaller battery and larger screen. This is probably due to a combination of more efficient 45Nm 8255 CPU (versus 65Nm 8250 CPU in the desire) and the new Sense which has surely been tweaked (eg. the faster boot time). http://en.wikipedia.org/wiki/Snapdragon_(processor)

The GPU is tweaked but not sure how it will compare with current leader Galaxy S.

I'm going to preorder one now that I know the updates are more than just a better camera.
Playing with the DHD last night the home screen seemed as fast as mine (fast) but the maps seemed to be more responsive.
