Bluelounge Jimi — USB Port Extension for iMac

If you love your iMac but hate having to reach around the back to use its USB ports, the Bluelounge Jimi is for you. The idea is simple: the Jimi plugs into the back of the iMac and curves underneath to give you an easily accessible, front-facing USB slot. It ain't the prettiest solution in the world, but it works.

$15 at Bluelounge.
