My MBP has a scratch from the very top of the aluminum case (on the inside) down an inch on the screen. I noticed it as soon as I opened the package. Bring it back, eh? Will they accept it or say, "you scratched it."
There's only one way to find out
So this is on the front of the screen, and not the aluminum on the back, correct? I think they would fix that, rather than dismiss it as a "cosmetic issue" like they probably would if it was down the back (depending on depth).
