I played yesterday with a guy who was using it and he says he likes it so far. He said if you're into numbers, it's good. I asked about accuracy and he says it's pretty spot on. I know it's small, but I think that thing on my belt might still bother me.
There was a huge review on some thread here a while back...although that was right after launch I believe, and who knows what all software work has been done since then on it.
