We're very well aware that some people are an absolute pain in the ass to shop for during the holiday season. You can always go the impersonal yet safe route by simply purchasing a gift card, but why not dig a bit deeper and find something that is cool yet actually a bit useful.
After searching through various tech/geek sites, we found this rad USB mini fridge and heater. This little fridge connects directly to your laptop for power, and can cool down a beverage or warm one up in about five minutes. A can of soda fits perfectly, and we'd assume that a cup of coffee would fit nicely as well. It is only $32, which really ain't that bad. Pick one up at USB Geek.
