Flickr user TSwartz has reported a problem with his white MacBook getting discolored on the palm rests:

The spots don’t wash off, I’ve only had the MacBook for two weeks. Genius at Apple Store told me to call Apple about it, as he’s never seen anything like it. My iBook didn’t discolor in the 3 years I had it — can’t be my hands. I don’t smoke, don’t use latex, etc. And for those who worry about my hygiene habits, thanks. I wash my hands.
