I feel that way with the Dell Streak 5 I got from my employer to test for my department. The 5" screen is incredible and once Dell finally got around to pushing out 2.2, the phone rocks.
I can't see going back to a smaller screen or inferioir hardware (1ghz, 512 ram). I did look at the Samsung Infuse (4.5" screen, 1.2ghz) but I've gotten this phone setup so that I know where everything is and to restore that on another phone seems to be too much effort.
(Hopefully, they forget to ask for the phone back)
