This New Dongle Instantly Turns Your MacBook Air Into a Touchscreen Monitor

Have you ever wished your MacBook Air was a touchscreen device? If so, this new dongle from AirBar is just what you wanted. According to CNET, the touchscreen sensor works by "sending up a light field that your fingers break by swiping and tapping," thus creating an interactive screen you can swipe on. The sensor bar, which is also available for Windows PCs, is currently on sale for the 13-inch MacBook Air only. To seamlessly connect your laptop to the AirBar, all you have to do is plug it in to a USB port and simply set it below the MacBook Air display.
