If you look in the sig, you will see that I am long overdue for an upgrade. I have my brand new 15" i7 Hi Res AG fired up and migrating my old stuff now! So excited! I do have a question while here: Will I need to reinstall the OS on the old MBP in order to restore it (i.e. delete all my old stuff)? Or will it do that automatically? That is, when done with the migration, will I be left with 2 duplicate computers? Thanks!
