My 3 week old (made in week 50) unibody has no faults at all..........no dents no scratches, no slanted keys the battery cover fits perfectly and the screen is superb......
Great. My two year old plastic one has no faults at all, either.

This isn't about one computer, it's about the series as a whole. And at the current point, the aluminum ones have a lot more issues coming out than the plastic ones.
