Heated Knee Pads, USB Style

Man, my knees are really cold! When was the last time you said that in front of your computer? Nothing is coming to mind.
Well, perhaps cold knees while computing is a problem for you, and a company called Warmmi has invented the USB heated kneepads. For just 20 dollars, you can jack it in and feel the warmth on your mid-leg regions.
Of course, if you are using a laptop, you don't really need this device, just push your computer to Knee-level. Now, if they could make a USB back massager, I can finally have some comfort.
