The screen on these rmbp are really easily scratched/chipped. For the mobility of these laptop, we would expected some durability from the screen too! I have had my screen chipped more than 4 times throughout owning this laptop. I take great care of my machine. Meaning i carry it in a laptop sleeve and clean my machine regularly. A grain of salt between the palm rest and screen will ruin your display just like that..... I am a college student and i take my laptop around to lecture for not taking... that is the most traveling ill do with these things and the display gets damaged just like that.
