I just ordered my first Mac, one of the new iMacs, and I picked up a few programs while I was at it, one of them being QuickTime Pro. What I was wondering was whether the code I got can only be used once, or if it's the typical 3-system deal. I want to give the code to a friend, so we can both get the Pro version, but not if I won't be able to register mine when my iMac (eventually) arrives.
