And yet certain people make manufacturing defects the users fault.
Personally, I got a flawless iPhone 5, but my iPad Mini had a chip on the beveled edges right out of the box. Im not going to bother exchanging because I dont care, but it is a problem that shouldn't be dismissed so quickly. If this is a coated aluminum then a crack can only be the start of a bigger problem as the chipping starts growing over time. I can feel the edge of the nick on mine so I can see why people would feel it is annoying and want the issue addressed.
