I do see a lot of iPhones with smashed screens but I've only ever seen two or three Androids with smashed screens (and no blackberries). So this probably means that either the androids don't smash easily; that android users don't drop their phones on hard surfaces (unlikely - these are humans we're talking about); or that the iPhone screen is so good it keeps working when smashed and the Android ones don't.
