I bought this computer, my first ever mac, and I'm in love, OS x is wonderful. But today while cleaning my MBP i noticed that one side creaks, the left to be precise, but the right does not. Should i go down to best-buy and return it before the 14 day return policy? Is this normal? Should it be replaced? I don't have any experience with macs apart from an old powermac g4 quicksilver, so I'm not sure if all of them are like that. My father says it looks like the gap is bigger on one side of the display than the other when it is closed. Has anyone experienced this?
