The guy in the office next to me just upgraded from a 15 to a 17 PB. When he first fired up the new computer it asked if he was upgrading from another MAC. When he said YES it asked if he wanted to move all his stuff onto the new PB. He said yes and it told him to conect the two with a fire wire cable and then restart the old one honding down the T key. It then proceded to transfer ALL his stuff - programs, files, setting... This total blew his and my mind. After about 30 minuts he fired up the new machine and that was it. I remember getting a new PC and this was a two day process. Apple Kicks Ass!
