I gave the update a chance, for something like a week. Finally put Panda back. I had hoped that the update might make it worth it. I have no idea what the update was really supposed to do in terms of performance but it's been a zero sum game. I don't give a flaming politician about live wallpaper or exploding gallery icons. I like Panda's pull-outs that go across all desktops and the alphabetical pull-up. The stock phone is really lacking in terms of app organization. Photo organization too. Your mileage will definitely vary.
