Well I'm new here and new to Macs. I just order a MacBook and Ipod Nano. I already have a 40gig iPod Photo and I run iTunes on my PC. When my MacBook gets in I plan to give the PC to my mom and just use the Mac. My question is can I run both the 40gig iPod photo and the 4gig Nano on the same computer/iTunes? Will iTunes let me create 2 seperate libraries 1 for each of them? Also how much trouble will it be to move my iTunes from the PC to my new Mac?
