I have a white macbook from late 2007. I know the plam rest cracking is a known issue and apple replaces this. From what I have read it is free even if you are out of warranty (I never bought applecare!) There is also a hairline fracture running from one side of the palm rest to the other. So my question is will they replace it even though I have a crack on the bottom case (which they don't replace in this procedure anyway) that was caused by a drop? Also the inside of my macbook is probably disgusting because I never clean it with compressed air or anything and I know crap falls into the keyboard all the time. Also the left side where the headphone jack has always felt a little loose and I can push it in a little. Here's the crack from the drop I've lived with these cracks for a long time because the closest apple store is 2 hours away and this is the only computer newer than 1995 in my house so I can't be without it for any length of time.
