I'm going to wait and see what people think of it on the iPad 3. I don't want to wind up with a slower processing speed or a quicker battery drain. I've got no reason to expect either of those will occur, but I'm not taking any chances.
The battery drain is already way faster than Apple or the fanboys will admit to, not that I give a crap what either say or believe. I only know that I've never owned any iOS device that didn't drain the battery way faster than it was supposed to, and that includes iPt1, 2, and 4, as well as iPad 1 and 3.
Oh, and one more thing....
I like Google Maps but I'm not sure I will like the Apple app they replaced it with.
