Got an ipad air the other day and have the original ipad and the ipad 3. I decided to restore my original ipad to new and started installing some apps for my young son. Obviously its alot slower than my 3 and air for almost everything but i was suprised to see that my original iPad is smoother than my iPad 3 rotating the home screen and any screen that has the keyboard up. In fact rotating any screen that has a keyboard up is smoother than my air. iOS 7 needs some serious optimization I guess.
