I'm new to Macs as of this past April. Got a 13" mbp. I'm thinking of getting an upgraded 13" or possibly a 15" next year. I'm looking for the least painful way to make the move. Is it at all possible to just swap my 13" system drive into the new one or will it not work correctly because of some differing hardware. If backup software would help, I also have the full version of SuperDuper! in addition to TimeMachine. The thin I dread the most is the re-installation of all my audio recording software.
