Well I am nw 10 days into my migration from windoz and I will not be going back. What took me so long was my own ignorance to how great this machine was going to be and how easy it would be to make the change. So, a quick question: It seems that most people have external drives for storage ad back-up. Is there a reason why it seems to be so prevalent? Is it the "I need to back-up just incase or just for getting all the music and pictures off the hard-drive" What are your thoughts and what is your "best choice" of drives?
