I know the saying "nothing is perfect," but this is ridiculous. So far I have bought 4 2012 27-inch iMacs with varying problems. 1st - dead pixels 2nd - dead pixel in upper right corner; small "nick" on the back of the case 3rd - dead pixels 4th (current) - NO dead pixels, but a small "nick" between the glass and the aluminum case on the right side of the monitor I would hope that Apple's quality control gets better over time. I have returned the first three iMacs because I will not stand for dead pixels. Some of the nocks and dings may be the result of manufacturing. In any case I may keep the iMac I currently have. There are minor imperfections that may not bother some people, but the iMac is a very expensive piece of equipment.
