Well, mine always gets me within 5 meters, and away from the numbers, it always gets to where I am on the map without much problems. I mean, yeah, there used to be issues with the GPS not locking, but that's more of a software issue I think since I'd see 10 satellites with good strength and not lock on to any of them.
As for Infinite-T, he really got one part down. If Samsung had better customer support, they really could have wiped Droid or the iPhone or anything else out of the market. Other than for the vast App Store, which is now not such a factor as Android is catching up, currently with 100k apps, the Captivate really has everything else down and it really does surpass the iPhone in every way possible. Oh well, it was all Samsung's fault, but w/e, it really coulda been something, eh.
