So I took the hefty plunge and purchased the 27" i5 from a local Apple Retail Store, believing that Apple would have finally resolved the yellow-tint issue from over a year ago, or at least it would appear in much less iMacs as it has sorta died down on the forums. Anyways, opened it last night, and continued copying over files to it today, only to notice that it has a slight yellow-tint issue towards the bottom 1/3 of display. I've already made a genius bar appointment......I even purchased Apple Care on it, so the total was around 2.5k, and I'm hoping for them to allow a swap for another brand new unit? Is this likely, or will they just simply wave me off to a repair or refurb route. After dumping so much $ on it, and even purchasing Apple Care, I wouldn't be satisfied for anything but a straight exchange to a new unit. Also, will they allow me to open it up right there and check to see that it doesn't have any display issues as well? Thanks.
