I have developed a nasty case of contact dermatitis on my hands, and I think it's triggered by a mild metal allergy to my MBP. Anybody have this? Anybody know where I might find some kind of a cover for the palm rests etc? I'm using an external mouse / keyboard at the moment. It's hard trying to track down the cause of the allergy but most of my time is spent on the laptop so... many thks!
