My Intel iMac has 3 USB sockets. One goes to the keyboard and the other two go to hubs. One hub has my iPod cable, printer and graphics tablet (one socket spare) and the other has three external HDs and my digital camera cable. There are two spare sockets on the keyboard but as that is in front of the screen I prefer not to use them to keep the number of visible cables to a minimum. They are also unpowered whereas the hubs are powered. My scanner is Firewire.
