I've been testing out the Droid for the last week and one item that's VERY noticeable is the differences in GPS. The Droid GPS gets a lock on location almost instantly. The apps that use the GPS turn off the GPS when they're not in focus and then turn it back on when they're activated. Even if the GPS is completely turned off and then its turned on while using Google Maps, it still gets an almost instant lock. It doesn't hunt in a large circle like the 3Gs and tracks amazingly well. Is this a hardware problem or software? Overall, the iPhone's user experience is hard to beat, but the way the apps interacted with the GPS and how quickly it got a lock made several location-base apps usable. On the iPhone, I always turn off GPS as it burns battery, but on the Droid I don't have to worry about that. BTW - I was carrying both of them side by side for comparison.
