I think the ipod works with USB1 but it will take forever to transfer files. In fact, the retailer will often check that you have usb2 or a firewire before selling coz people can't live with the slow trasnfer speed. For exmaple, check with John lewis. Or better still check the prcie of gettign a firewire installed.
