I would appreciate owners of the new MBP 15" C2D matte would provide feedback if their system has a grainy display or not. Please include a the date when your order shipped (if you bought it online) or when you purchased it in a store. I bought my system on December 20 but have been reluctant to open it after I have seen reports of grainy screens on various forums. This is my very first Mac so I'm a bit concerned about opening it. I don't want to get dragged into one of those 1 - 2 month issues many seem to be having with Apple on a more frequent basis. In a related question, is there a way to determine the build date of my system based on say the serial number? I ask because my research online shows that Apple may have slowed/stopped production of the 15" models earlier this month (link) I would appreciate feedback.
