I bought a MB mid January which came with a defective lid. I sent that one back and Apple shipped me a new replacement. I have had this MB for a month and so far no hardware problems or software problems. But I have noticed that above the screw closest to the microphone and headphone the case bows and separates a little from the wrist rest. I've contacted an Apple rep who helped me with the replacement MB, who btw was very nice and helpful, and he told me that more than likely if I sent it into repair they would claim the MB with in spec and just send right back. Two weeks without my main computers sucks. Here is a pic of the situation what are your thoughts?
