There is a small outwards dent coming from my new MBP's case on the bottom side near the last screw on the right side (in the orientation so that you can read the writing). Its not very noticeable, but I feel that the case is not fully flat in that spot. Should I take it back for an exchange? There are no apple stores near where I live, and its not really a huge issue. Is anyone else's MBP similar?
