Hello, I've done some extensive research into why my iPod Touch doesn't work with my perfectly capable G4 iMac. It's because it has a USB 1.1 port on it. There have been a lot of people having problems like mine, and the vast majority seem to stem from having USB ports that aren't 2.0 I believe that this is to get us to buy new computers. There is no reason for the touch to not work with USB 1 (although it would be really slow) and there is, again, no reason why they couldn't make it compatible with both USB and FireWire. Pffft. etc.
