Okay, here's the story. I dropped off my iMac at the Apple Store about last month for a optical drive replacement. Got it back, and the optical drive works perfectly. Fast forward to today. I just discovered a chip in the aluminum on the iMac, on the botton. I know for a fact that the chip was not caused by me, because the iMac has been sitting on the desk basically untouched since, and I transported it in the original box. So my question is, should I bring it back and complain? On one hand, it has been a month, and the iMac is running perfectly. But on the other hand, I'm kind of pissed about this chip in the aluminum. It was in near-perfect condition prior to the repair. What do you guys think?
