The duaLink cable for iPod and iPhone contains its own miniature USB hub, a single USB connector on one end, and two iPod connectors on the other end. If the promise of charging and / or syncing multiple devices from the same USB port hasn't blown your mind, the company has been thoughtful enough to place the whole shebang in a housing that seems to be a little more durable than the (admittedly not so durable) stock Apple cable.
