If you're like me, your hands not only get cold during a shoot or while outdoors, when you sit down to edit on your computer, then they really get cold. I now use a heated mouse and have several great products from http://www.heatedmouse.com to keep my nice and cozy. No more space heater, at least I don't keep it cranked up as much -- the the Warm Mouse and the warm Heated slippers are both really great & my favorites. I picked up the warm heated shawl too, but so funny -- my wife stole it from me before I could try it out and uses it in bed with her laptop so I might want to get another one... one of these days. Ha ha.
These little gadgets seem to get power to make the infrared heat from the USB on your computer, so no need to plugin otherwise than right into your computer. Pretty neat, thought I should share. Cheers!
