It seems to me that if I have my iPod and iSight both plugged into the firewire ports on the iMac, file transfer with the iPod is considerably slower. At its regular fastest, a few songs can be transferred a second. This can go down to one song per 10 seconds.. this is also while the computer HD isn't really doing anything. Unplugging the iSight always seems to speed it up. Is this an issue with other people?
