Most places I stay have coffeemakers. I don't drink much of the stuff, so mostly I put them away so I don't break the urn.
Then it dawned on me - all it is is a little water heater. It turns out to work pretty well with instant oatmeal. Dump in the right amount of water, empty the little envelope(s) into the bowl, put it under the spout, check your email and there it is. Next up - ramen noodles.
