Heated USB shawl

A typical winter evening might be me, bundled up on the couch watching a favorite TV show while monitoring Facebook on my laptop. But there's one thing missing from this picture: a heated USB shawl. This plush wrap is powered through your computer's USB port and can double as a lap blanket. Keeping office-chair-induced lower back pain in mind, this gadget can also be folded up and placed behind your back while seated.
