my new rMBP 15 2.3/16/512 has small tiny dent at the bottom. It is there on the day I got it, two days ago. I have been quantumplating whether I should exchange it. It was just enough to see when you look at the angle or feeling it with your hand. No functionality issue, just this minor cosmetic. The problem is I know it is there now. I am trying to get over it, but I keep on thinking. Heh, I spent near 3k. I demand nothing less. This is not my first Mac, the 5th to be exact. Is that reasonable to you guy if I exchange it?
