We've always been cursed with cold hands and feet, probably because we sit at our desks for 15 hours a day. A space heater and sock combination will protect our feet (somewhat), but what about our hands? Thanks to the "World's Smallest Big Heater" from Sharper image, that's no longer a problem.

The heater is a compact 150-watt space heater that fits nicely onto your desk, and has a high, low, and even fan mode for summer days as well. Better yet, it's only $39, has a neat blue ring, and turns off by itself when you flail around wildly to the Numa Numa song and accidentally knock it over. – Jason Chen
