ok, i highly doubt the new mbp is going to come out within the next month, but IF there is, i have a question. say i buy the current mbp this wednesday, can I open and use this macbook pro for the next 14 days and still exchange it if the new mbp comes out? Or does it have to be sealed with the receipt on hand and no scratches on the box (and etc...)? i'm just a bit confused on this 14 day return policy, thanks.
