Ok, So I have had like 6, Count em, 6 replacement Aluminum Macbooks at this point. All 2.4ghz, the most recent replacement was December 20. I recently discovered that when i open the lid of my computer, the lid slightly rubs against the body of the computer, i also noticed that it has sort of worn on both the lid in a spot and the body in the spot they have been touching eachother. It is only on one side, the right side when looking at the screen. I also noticed it looks like the gap between the lid and the body when the lid is open is greater on the left side (the side clearing not rubbing) than on the right side....Needless to say, it is a defect, and I need to take it into the Apple store. Where my question lies, is do you think that I deserve/should ask for a different machine rather than going with another replacement...I have had so many problems with these new MacBooks, and I think that at this point it is a lost cause for me. i would rather go with a different apple machine if they let me. I have already contacted the manager and explained the situation and have scheduled an appointment for later today...What do you think will happen/I have the right to ask for?
