My early 2008 MacBook has extensive cracking on the palmrests and around the keyboard and screen - I can almost see into the computer because a long strip of plastic is missing from one entire side of the top casing, and that can't be good at all. If I take this to the Apple Store, are they likely to turn me away because I fall outside of a 3-year repair limit I've seen mentioned? What are your experiences with how strictly they enforce that rule? I've never had repairs done before. I figure that this is my last chance because they won't keep the parts for a discontinued computer around forever!
