I've had my iPod mini for a week or two now, and I've started to see how a dock might be nice so I can just set it in there instead of looking around for the end of the cable. Another problem I have is that my old iMac only has USB 1.1, and my iPod only came with a USB cable. Do the docks come with a USB and FireWire cable, or if I buy a dock will I still have to buy a separate cable for FireWire?
