Just received my MacBook Pro 15 over Christmas break and while using it I've noticed a few flaws so far. One is the graininess which is already mentioned on the forum and the other is paint peeling. The left side of my LCD panel has a slight discoloration; there is a white "bleached" area within the aluminum frame. I tried cleaning it with a soft cloth and water but the stain stays. Has anyone else experienced this? Should I exchange my laptop? Has anyone successfully received a new MacBook Pro after complaining of graininess or surface defects? I know its just cosmetics but I laid down a lot of dough for this equipment and I expect a certain degree of perfection.
