I got mine last Tuesday, switched to Verizon, wife got the iPhone 4S to replace her iPhone 4 from AT&T.
In any case, aside from battery life which is easily the worst I can recall going back for some time now, I have no complaints. Service is great, LTE is wicked fast, I'm adjusting to Android, and call quality has been really solid.
Will probably root it and go with stock Ice Cream Sandwich when that time comes, so far I just haven't been impressed with "sense" it has taken me a lot of time to get things to work the way I want it.
That being said, the screen really is amazing, looks better than my wifes iPhone 4 (4S is on order).
Having nothing to compare it to other than my Blackberry Bold 9700 any real review I could give wouldn't have the proper perspective so I leave it at this...
PS: I was holding out for the Galaxy Nexus but got tired of waiting and as more and more little things came out I was less and less impressed, other than Ice Cream Sandwich I think what I have will do just fine.
Can you give some example of the poor battery life you're getting?
