Now I've had this on my ipad2 for a day I have to say I still really like it. The only thing I've found that I don't like is the folders. I now get this little bubble up in the middle of the screen that shows 9 icons at a time
Battery life is still as amazing as it always was. 19 hours standby and 1hr 10 usage and still on 100%
I usually get around 3 weeks. I always get the 2 week warning that it hasn't been plugged into the mains to sync with iTunes.
3 weeks on a single charge you must never use it I'm lucky to get 3 days on any of mine..
