This sort of thing doesn't bother me, but if it bother you, my new iPad has a pretty noticeable yellow tint. I noticed it as soon as I fired up Safari, and when I placed it next to my iPad 2 it became very obvious. But it also made me think the color replication on my iPad 2 might not be so spot on either....
No worries here, I'm happy with it.
Attached is a pic.
That is awful.
