Since the iPad2 is pretty darn fragile I can’t see myself using anything but a case. It doesn’t have to be the kind you can throw down a hill or against an office wall, but it does have to protect my investment. I favor the garden-variety notebook style myself with either an edged sleeve border or an effective clip edged border. Either way, it should be thin and fit tighter than a cats meow. Also, make no mistake, as many iPad owners would likely pay through the nose for quality. Then again, what do I know.
