Pros: The Screen is amazing.
LTE ( it's also a con in my opinion).
Ice Cream Sandwich of course.
Big software improvement but still not there yet.
Verizon call quality with this phone is good not the best I've seen.

Cons: 4 hours battery life, the thing die before lunch.
Expensive but resale value is not good.
Feel cheap, too plastic.
Still lag, not as smooth as iOS and WP7.
The camera is down right horrible.
Ecosystem is a mess.

LTE is not mature enough. Returned it, stick with Galaxy S II for now.
