Of all the dumb USB external gadgets I’ve seen, this one actually seems useful. Simply plug this gadget into the USB port of your computer and you instantly have a way to keep coffee, soup, hot coco or whatever warm. As an added bonus, you have a 4 port USB hub at your finger tips. it kind of seems an accident waiting to happen but if you know a desk tidy person (I know none) it may make an unusual Christmas gift. Priced at Only $3.99.
