Sweex Micro USB Hub
I'm pretty sure we've profiled a USB hub like this one before, but the External 4 Port Micro USB 2.0 Hub, made by Dutch manufacturer Sweex, seems like a pretty cool idea: one Port in the back to plug into your computer, four in the front for devices and the input plugs can fan out of their container if you've got devices that take up extra space. For some reason the site's specification page doesn't list the dimensions, but given the manufacturer's claim to travel size I'm wiling to bet it's pretty portable.
