There's a new campaign on Kickstarter for something called the "Bedchill", a big table on wheels that sits across your whole bed so you can work and eat while sitting up in bed. It's basically a TV tray the size of a desk, with charging ports and Bluetooth speakers built in.
They were trying to raise $23,000 and they got that in the first hour... now it's up above $320,000 and still going strong!
