My macbook pro is about a week old. I read about the horror stories of palm rest aluminum pitting for macbook pros, so I started to look for any signs of it. To my surprise, despite taking care of the macbook I notice these very tiny( hard to see with naked eye) circular dents that looks like someone made a small stab at it with a needle. I found three of these "dents" two of them being near the lower edge of the palm rest and one next to the shift button on the keyboard. I realize I am being a bit ocd about this, but I want to know what caused it and if I could prevent more from forming. I guess they could be manufacture defects but still.... once you know they are there, you can't unsee!
