Hello! Sorry if this has already been posted, I couldn't find a posting about this. I currently own a 2.4GHz MacBook Pro, purchased it about a week ago, and when I took it out of the box, the lid was warped, well about a week later (today) the warping has pretty much tripled since last Friday, and I am taking it back to the Apple Store for a replacement or refund. My question is this, well actually a couple questions: 1. How common is the warping issue? 2. If a MBP is not warped when taken of the box for the first time, how long does it usually take for it to start warping? 3. Does the change of temperatures effect the warping, as the MacBook Pro is made with aluminum and metal expands and contracts with heating and cooling? I am thinking I will just get it replaced, but I am also thinking of getting an iMac, something that won't warp. If you have any reasons to convince me to stay with the MacBook Pro, or go to the iMac, please tell me as I have until Sunday to decide. Thanks in advance!
