As in previous releases from Apple, people are complaining about problems, in this case related to the white Macbook. It seems their laptops are having some discoloration problems and some pics are around the web in forums about it, though some of them seem a bit weird. In any case... judge them by yourself.

In the forums they talk about having tried different cleaning products with no luck and that this problem started after just 2-3 weeks from the purchase of the Macbook. In any case, I would not consider this a major problem as if it were a real design flaw, many more people would be complaining of these problems. It could be a problem in some units only or maybe just a rumour and some photoshop playing. At least it is what i want to think as I ordered mine before knowing this and I will be getting it in a few days.

If I get the same problem i will create a new thread to get a posible solution to the problem as Apple does not cover aesthetic problems.
