A don't use any protection for my MBA, only a sleeve when there's a need to carry around. I don't use anything for my iPhone either, because it ruins the aesthetics of the phone. But then, I don't know why, I have this mentality that iPads MUST be used with a case. When holding a 'naked' iPad, it just seems 'wrong' to me. Everytime I buy a new iPad, I have the urge to immediately buy some black leather case. This is not because I'm worried about dropping it, no, I usually won't care about dents and scratches. It just looks classier, more professional when 'wrapped' in leather cases than when being 'naked' - it just looks like a toy for kids to me. Do you guys share the same thoughts?
