I have a 450 MHz iMac g3 with 256mb of memory. I'm running OS X 3.9 (Panther) wit iTunes 6.x (last version) and it works great. Do I have anything to fear from loading iTunes 7. I think that I'm getting a new iPod for Christmas and I want to be prepared. I already know that I have to deal with slow syncing with USB 1.x. Let me know what you think.
