When this was first reported I thought it turned out to be a hoax, but I was cleaning my black macbook yesterday and the coating has definitely come off in a 1 centimeter square space on my battery. The bare plastic actually looks glossier and nicer than the coating, but I'm not about to start peeling away. I got my macbook on day 2 but I haven't been abusing it at all. Did anyone else have a peeling issue and what did apple do about it for you?
