My release day iPad 1 and release day iPad 3 have no issues and came in perfect cosmetic condition. Everything here is way overblown. You have understand forums like this *cater* to people who are having issues -- so it seems like most people are experiencing them.
It also attracts obsessive compulsive people (I mean the real deal, not just throwing that term around). In addition to going through 15 iPads to find a perfect one, they likely touch their doorknob 5 times before they leave the house, and turn around in a circle ten times every time they use the toilet.
I agree with your statement. I had no problems with my original iPad and my new one looks fine as well. Does the screen take on a different hue in different light - yes, but so does everything else. Right now sitting inside my screen looks white, white with a tad bluish tint. Outside on a cloudy day, the screen does take on a bit of rosiness. But I also wear transition lenses glasses which may play into the whole change of color.
I know that I could drive myself crazy trying out and returning 5 iPads. I guess I could consider myself lucky - lucky that either I got one of the few perfect screen iPads or lucky that if I didn't, I can't tell the difference and it doesn't bother me. It's been enough of a struggle trying to find the perfect case...
