The bezels are too thin now. The amount of times I find my screen "unresponsive" only to realize a part of my hand that is holding the phone has folded around front and is just a mm over the bezel and touching the screen is maddening. And I know I am about to get hit with "you're holding it wrong", to which I say, it's the same way I have held it since iPhone 3G. Also, if a design is so delicate it can only be held in one exacting manner, it is a poor compromise of a design.
