I "restored" my brand new 3GS with my 1st gen's backup I made yesterday before updating to 3.0. If I were you I'd restore on your PC, then create a new backup on the macbook after that. not to get too off topic, but how do you like the MBP? I've got my eye on that 17"er. I'd prefer the 15 but they got rid of the expresscard slot.
