My hands have a tendency to get cold while I'm using the computer, especially at work where everybody seems to like to work in subzero temperatures. This is the perfect solution: A usb mouse that emits heat to keep your hands warm! It comes in a variety of colors and has a nice ergonomic shape to it.
The temperature stays at a warm 45C degrees but also has an on/off switch if it gets too toasty for you. And don't worry, the mouse is made of a heat resistant material to keep the components from getting damaged. At $23, it's not a bad price to pay to keep your hands warm while you're surfing the web!
