My girlfriend just got an mbp 2.0. I love it and it is an excellent machine. It works very fast and I love the OSX. However, I have sweaty palms and after using it, she always yells at me because it leaves an unslightly light-brownish stain on the palm rests below the keyboard. Should this deter me from purchasing one? (I was going to order the 2.16) I mean I am always leaving these ugly marks on it. Perhaps, it will cause eventual damage to the case. Do any of you have any experience with this problem?
