So, how many of you have some yellow tinting on their new iMacs? I just got my 27" and I have a bit on the bottom half. I really hate to return a BTO that is otherwise perfect. No pixel issues, flickering or anything. And the thing is so fast and quiet. If I hear that many people have tint issues with their new iMacs and is a common and issue then it's probably not worth playing the lottery game. If 90% say their's is absolutely perfect then exchanging mine is something to consider I suppose.
