Hello all...I just bought a Power Book and a "Thin Fire Wire" wire. How can I move or make my Power Book have the same info as my Imac? Also, depending on which computer I use the most, can I make the other computer have the other's info by using this wire...in other words...can I transport info from one computer to the other with this wire? I want to use my Imac as my main computer and just 'update' my Power Book weekly so that it will have the same info or 'emulate' my Imac...thanks.
