Google and Asus have joined forces to launch the $85 stick that when placed into a TV or monitor transforms the screen into a computer.
The Chromebit device, which resembles a USB key or dongle, can be plugged into any HDMI port and turn the machine into an instant computer.
It was first revealed by Google in April and goes on sale today (17 November).
The device weighs just 2.6 ounces and also features a USB port.
Using the USB hub users can then plug in Bluetooth mouse and keyboard devices.
Running on Chrome OS, the computer can be used to surf the web, download apps from Google Chrome and play movies, games and TV shows from Google play.
The device is powered by a quad-core Rockchip processor.
The device is available in the US via Amazon and Fry’s and will soon be available in Australia, Canada, Denmark, Finland, Japan, New Zealand, Norway, Spain, Sweden, Taiwan and the UK.
A $24 version will be made available for Google for Work and Education customers in the US and Canada.
