The thumb scope on my moms' 13" MBP seems strange. Looking strait down on it, the left side has more of a curve and the right is more angled. Does anyone else have the issue? Click on the picture to make it bigger notice the top curve is more curved than the bottom. Any one else have the problem with theirs? Yes its small, but I would imagine that because its all machined, it would be purr-fect.
