all panels are different!Besides the glue and backlight bleed issues, the other significant screen issue with both the iPad 2 and iPhone 4/ 4s is that they mostly suffer from an insanely putrid yellow color profile that was not a significant issue with earlier models. You can make the warm vs cool argument, but I'm sorry, white is a friggin' COLOR - and white is NOT light yellow. The yellowish color profiles are extremely irritating to me, but I've seen this on almost every iPad 2 and iPhone 4 / 4s that I've encountered. I sure hope this goes away with the new iPad.
And no this does NOT go away.

I've been through 4 exchanges of the iPad 2: 2 of them had a cool/blue tint while 2 others had a yellow/warm one.
