Ok basically, I've just noticed I have the infamous crack on the bottom case of my white macbook. Now i've been reading up in random places, and apparently they replace it for you. (I bought my macbook in march 07). http://blueeyedcreature.net/apple/CrackBook_close_up.jpg So I was wondering if I go to the apple store soon (next monthish) that they'll replace it with another whitebook. But me being my greedy little self, believe that if I play the waiting game, they'll have to give me a glassbook because I have 2.4Ghz, 160gb 2gb. Surely they can't give me an inferior machine. Oh and P.S. Would I have to back-up my data? I.e. They just give me a fresh macbook.
