I have an iMac G3 with firewire and I'm cosidering buying the new 80gb ipod. I understand that firewire is no longer supported and that USB 1.x takes forever to sync. However, my iTunes library is on an external harddrive and I'm thinking that I could do my initial sync using my son's PowerBook g4. He has iTunes on his g4 as well could I get his iTunes to point at my library on the external drive instead of his on the internal drive?
