Hi All, Just wondering if other have noticed that the main place where the trackpad is used (not around edges, but the circumference) looks greasy? I've had a macbook pro with 5 years use and the trackpad does not look as though I used it with grease on my hands (which I do not). Just curious to see if this is a different quality trackpad. (picture attached) you can see that it looks a bit greasy looking. Just interested in knowing if anyone has noticed this difference from having previous macbook PRO's compared to new macbook air?
