Better keyboard (the D-pad blows)
Functional 8 MP camera
Flash (I know 2.2 will have it, but this is a wish list after all)
Basically, just MORE of what the Droid already is. You just CAN'T argue with how complete this phone is. OK, maybe you can, but really, it's a great device IMO. I haven't liked a phone this much since my Voyager.
