for all you 1st time iPad buyers...may i make a suggestion?
Don't buy a case right away. Hang out with your iPad for a day or and only then if you feel you need a case - buy one.
Screen protectors, skins, cases, blah blah really do make this amazing machine ugly and heavier. I would rather have a few scratches on the back then endure some of the things I see being suggested in this thread.
I'm sure most of you will tell me how much you need one but I promise you that 90% of the time you don't.
I was back and forth about whether or not to have a case on my iPad 1. I ended up going with a relatively thin rubber case from Incase, but that was mostly for grip rather than protection.
