Greetings MUGgers! I've noticed that my macbook already has that "hairline" crack that everyone's been talking about. I'm actually shocked since I got my MB last year on April 2008. Based on the threads, it seems that such a problem has been fixed and replaced by authorized resellers. My problem is that I see the crack already but I'm not sure if it's "worthy" of a replacement already. It's already March 2009 and my warranty is expiring. It's already there but then I don't know if the stores will allow it to be replaced. It seems kind of disheartening that my somewhat new macbook had to get a crack right after the warranty expired. The crack's already there but then I don't know how much longer it will take for it to become bigger. What are the requirements/conditions that a macbook's shell can be replaced? What should I do about my MB's condition? EDIT: This is the clearest picture that I could get of the crack on the right-hand side of the laptop. There's really a crack already. This one what I noticed on the left side of my mac. It seems like the case is warped. There's a small gap between the lower case and the top case. Same as above. This is a "crack" that I've noticed from before. It seems different from the first picture I showed, but maybe it could be an indicator as well.
