Awful Keyboard of the Century.
I have the MacBook Pro and can confirm it's keyboard is truly awful. I have a can of air on the shelf for a 4 month old laptop and it needs using every week to blow out crap so the keys work. Truly awful design.
Contrast with my MacBook Air 2011 which still worked after trips to Africa and used on a bus with more red dust than Mars yet a Pro machine which never leaves the sofa craps out every few weeks.
