Smooth update for me. They fixed many bugs that really had bothered me with 2.1 I had previously been unable to properly change the date of existing all day calendar events...now fixed. I love that the keyboard doesn't pop up in messages. The phone is snappier and seems to utilize memory more efficiently. My battery life seems similar to previous...no discernible difference. Most of the gripes are from overreactors, impatient kids, or from trolls. This 2.2 went off without a hitch. I'll put 2.2 on my wifes EVO tomorrow.
