I was using my Mac in the sun when I noticed that the edges of the trackpad were noticeably shinier then the rest of the pad. It looked as if it were a part of the thing that is not used much, and it was contrasted against the rest of the trackpad. I use my computer everyday, for maybe 5+ hours with the built-in pad. Do you think that Apple's anti-wear coating has worn off or something? I am kind of worried because the texture of the shiny part is much different then the rest of the pad, which has been used excessively. If I wear through the thing, is it covered by the normal Apple warranty? (I didn't buy the AppleCare plan.
