I sold my 1st generation iPad and bought the iPad2 and have some concerns/questions... I've read others' reviews about the battery not lasting as long or as well, and I immediately noticed this right off the bat. True? Also, I have been finding the Internet connection to be a little worse - even though I show Internet connection, a Safari internet page frequently takes forever to download, then it will say it's not connected so I have to restart my iPad to get the "connection" back, and don't like having to do that also. Finally, lately when I try to touch an App (or any "box") on the home screen to open it, the screen has been freezing up and I can't touch anything. Anyone have any similar problems?
