That picture makes my screen look good, and I am not happy with my screen. My iMac is used only for my photography business and the slight color gradient at the bottom just bugs me. But the display is gorgeous if you are only looking at video or photos and not gray bars or solid colors. I can live with it and enjoy it until a fix is found. I don't do highly color critical work, and I have work arounds.
I think the real problem here is that some people are pickier than other people. Apple should know that there customers are generally going to be more selective, just because we bought Apple computers.
