I bought a Macbook from someone on eBay (white model) around Christmas of this past year. AppleCare for it runs out sometime in 2010. With use, some of the letters on the keys have started to wear off. There are also two chips on the top of the laptop in the corners. I have a Genius Bar appointment tomorrow for my iPhone and am thinking about bringing my Macbook along as well. Would Apple replace they keyboard and possibly the part where it's chipped? Thanks.
