I've got an Otterbox Defender for my iphone4 which I love because I'm a bit clumsy and this case means my phone has already survived 2 drops onto the pavement unscathed. So, I'm thinking that I should get the same kind of case for my iPad but the reviews for it are mixed, in particular I'm concerned that there is no integral screen cover for it so now I'm not so sure. Anyone got one and care to offer a review? Or suggest an alternative? I need something bombproof!
