Not sure why the other yellow tint thread is closed, but I felt obligated to give an update on my situation... After going through 12 new ipads I was shocked to actually land on an absolute PERFECT one on my last try. I had become completely convinced that there was some kind of defect with all of them and had pretty much given up. The only reason I picked up #12, the perfect one, is because I accidentally took the one back I had finally decided to settle with, and was left with the horrible one. When I realized my mistake, the Apple store was closed for the day and when I called the first thing the next morning they informed me they send all returns back at the end of each day. So I was left with little choice but to exchange my horrible one and roll the dice. And so I'm here to tell you there are absolutely perfect models out there without a trace of yellow, discolor, anything, anywhere. My keyboard looks perfect. The screen is absolutely phenomenal. I came to realize in my exchange madness that there seemed to be two types of back-lights. I'm not talking about the tint, I'm talking about an entirely different light source lighting the ipads. On almost all of the black ones I had, the light was of a warmer nature, and somewhat dull. Those same black ones are also the ones that had the 'yellow' tint somewhere... either in a corner, on half the unit. The second back-light is more of a cooler tone, more akin to a fluorescent light. And I found these mostly on the white ipads. These white ones usually had an annoying red tint instead of the yellow. The one I had finally decided to keep before I accidentally took it back was this kind. A White one with reddish tint. So then I got home with basically my last ipad and it was perfect. It is a white one with the cooler back-light... but NO RED TINT. No tint whatsoever. I'm not posting this to make anyone feel bad who still has one with tint on theirs... because I know reading this would have annoyed me two weeks ago. I'm posting this because I think it's unacceptable that Apple would have such lousy quality control that so many people would have to go through all this hell. And maybe if enough people don't stand for it, they'll pay closer attention to what they're charging $800 for. Because I know I could have just as easily not wound up with the one I did, or could windup with a bad one next time.
