2.8 inch screen though.. ick. That kind of screen size might have worked on the BlackBerry's, but I can't imagine how sucky it's gonna be to use a touch screen focused OS on a screen that small.
As I see it, the top Android phones on each US provider currently are:
* Tmobile - N1
* ATT - N1 (actually, the only decent Android choice on ATT so far is the N1)
* Verizon - HTC Droid Incredible
* Sprint - HTC EVO.
For those who absolutely insist on a hardware keyboard, the only decent options I know of are the Moto Droid on Verizon, and the upcoming MyTouch Slide on Tmobile. Both are less powerful than the phones listed above, but the Moto Droid is still a pretty darn nice phone (particularly after the recent update to 2.1), and the MyTouch Slide looks like it'll be the next best hardware keyboard option.
(HTC Desire looks nice also, it's almost identical to the N1. But I haven't heard confirmation of it landing on a US carrier yet. :-( )
