I am really debating on whether or not I should pick up the new macbook. The thing that concerns me is the durability of the glass trackpads. I use to own the blackbook, and I noticed that with regular daily usage, the trackpad started to lose its texture and the surface looked like it was sanded down (especially in the middle). Now I realize that this doesn't effect functionality at all, but it was just an eye sore to look at. Can anyone who already purchased the new macbooks give their input on this matter?
