Today I went to an Apple dealer in Amsterdam to check out the new Macbooks. The two versions of the Macbook were available in the showroom to play around with. I noticed immediately that the screen of the 2.4ghz Macbook looked totally washed out, while the screen of the 2.0ghz version looked absolutely fine (although not as good as the macbook pro, but really fine). The difference was quite big, it was especially apparant with the leopard desktop background and white letters appeared too fuzzy. I asked an employee to explain this to me. He thought at first that a setting was wrong, but we checked it and the settings were exactly the same. He couldn't change the washed out look and didn't have an explanation. He agreed with me that the 2.4ghz screen looked quite terrible, but he hadn't heared anything from Apple or costumers before. We checked the screen version and the washed out one was 00009C8C, and the good one was a 00009C89, so apparently this doesn't say anything.
It seems to me Apple is having problems with the display quality of the Macbook because such a big difference can't be a normal deviation. That would also explain the different opinions about the screens of the new Macbooks. The employee actually discouraged me to buy a Macbook now, because he couldn't garantee a refund if my Macbook was also washed out, because, as he said, they relied on Apple's guidelines and hadn't heared about any production errors yet.
