I am considering buying an Ipod, but have several questions. (1) I seem to remember seeing somewhere that you could sync your Ipod with up to three computers. Now I don't see any reference to this, other than the home network option. What is the deal, can it be synced to more than one computer (i.e., a home Mac and office PC?). (2) I currently have Itunes and a bunch of songs I purchased via Itunes on my work PC. Once I get an Ipod and a new Mac for home, I assume that I can sign in on Itunes at home (with the Mac my new authorized Itunes computer) and all the music I purchased will be automatically downloaded onto my Mac via Itunes. Is this correct? (3) If something happens to your harddrive, do you lose all the music you purchased via Itunes? If so, what is the best way to backup the music you purchase on Itunes in case something happens to your hard drive? (4) If I use my Ipod with my work PC and later want to use it with my Mac instead, is it difficult to reformat the Ipod for use with the Mac instead of the PC? How is this done? Am I better off not syncing the Ipod to my PC if I am getting a new Mac in the next couple months? I would appreciate any help with these questions. Thanks!
