I don't know what to say, I thought I didn't have this problem, as it hadn't started but now that just about a year has passed since I bought my Powerbook it is starting to develop black dots. The aluminum on the palm rests is corroding, also called pitting. It is a reaction of the body chemicals with the aluminum and can get pretty bad. I've attached a picture so people can see what I am talking about. Although mine isn't as bad as the picture, it is getting there and Apple will do nothing about it since it is purely cosmetical. I guess I'm just pissed right now, I know I can use clear PDA screen protectors and the such and I do right now, but I cannot say which one are uglier the dots or the screen protector thingies. I'm thinking about taking them off again, I don't know. Fixing this, what I'd need to do when it becomes really bad, would cost about $200. I don't know what to say, I guess it is just a computer but it still is bugging the hell outta me.
