Okay here's the deal. I looked through the yellow tint threads and sure enough noticed that my high res AG had it. At first I dismissed it as poor viewing angles. I calibrated the LCD, which seemed to make it a bit better. But it is not a matter of viewing angles. I tried the test on my friend's old blackbook, and when viewing the screen head-on, the bottom square definitely looks yellow, BUT, when tilting the computer back, changing the viewing angle, the square turns white again, thus, a result of viewing angles. The same thing on my HR AG doesn't change the color of the bottom square, it stays yellowish. So I'm pretty much convinced that it's a real issue, at least to some degree. I'm considering taking it back to the Apple store, or at least going there and seeing how their display models look. Something tells me that nearly all HR AG models (the current shipment that's out right now) suffers from this, and that my replacement will be the same. Does anyone think this is true as well? Should I even bother trying to swap it out? The yellow tint threads have several people that are going through 5-6 exchanges, and all still getting the same problem. Any help is appreciated.
