well thanks all for replies...i had an emergency while working overseas - my MBP logic board fried and I could not postpone work for the week it takes to get parts from Singapore so I had to buy a white MB, loaded my 4gig mem from the dead MBP, installed Leopard using the TimeMachine backup from the MBP, and 30 minutes later I was back in business, sans 46,500 Thai Bhat. But it was worth every penny! The mb is doing everything the MbP was doing: FCP, Motion, Compressor, and a bunch of 3d tools and Protools just as good as the pro was doing. Funny, the MB feels like it's built like a power brick and the MBP is just cheesy and always breaking down...But thank buddha for TimeMachine and apple architecture!
