From the land that gave you tentacle porn comes the tentacle-like USB hub from Buffalo. Even better than the USB Rota-Rota Hub, this USB hub from Japan spaces each connector far enough apart so there's practically zero chance of devices colliding with each other.
Convenient, yes, but not powered, so placing four USB hard drives on the end of this will probably overload the USB port on your computer. Go for something light, like USB mice and USB card readers. The hub is compatible with pretty much all operating systems out there, and is available for $21 for a four-port version and $17 for a two-port version—neither of which will do unspeakable things to girls wearing school uniforms.
