USB Heated Shawl

I’ve heard of electric blankets, but to get a USB Heated Shawl? Boy, the office heater must not be working then if you ever need something like this. This $29 desktop accessory will require a free USB port (duh!), and even comes with a button to hold it in place around your shoulders as you hammer away at the keyboard. Want to know of a much cheaper way to keep warm? Get a much thicker shawl, or at least wear several layers more. That ought to do the trick.
