The USB Cup Warmer
It's nippy outside; think of your coffee mug, won't you? We don't think this USB mug warner is actually tethered to your computer all the time (it only has 5-inch cable) so it's probably not as dangerous as it looks, but it may be just as useless (er, we mean useful, like all USB-powered toys). After all, we're not types to leave a cup of joe sitting around for long anyway, but if you are and need another fix from that USB fetish, this may well be the perfect marriage of your favorite hot beverage and the unintended reapplication of a device interface.
