Durability of plastic screen on latest Retina Macbook Pro?
From someone who has the 13 inch MBPr, I have some comments about the screen.

Pros:
-incredibly sharp
-Fantastic colors and contrast
-Very bright

Cons:
-The glass- let me explain. Initially I notice that the glass did not seem particularly durable but, decided to get in anyways seeing as I wanted something new and powerful. My suspicion was correct. My screen has a huge scape across the center due to what i can only assume is the keyboard. I also have tons of those small chips/divots/dents (whatever you want to call them) all over the top half of my screen. I am not the person to mistreat their electronics. I always handle them with care and constantly clean and disinfect them. So it was a bit of a surprise to me when all of this damage occurred to the screen. Apple definitely made a mistake with this one. I am yet to go and get it checked out but judging by other reports i have doubts they will be willing to replace it.
