The Wall Street Jorunal:

The Neonode AirBar, announced Tuesday at CES 2017, is a $99 accessory that turns a 13-inch MacBook Air screen into a touch screen. It’s also proof of my longheld suspicion that a touch-screen Mac could be incredibly useful.

Clip the magnetic AirBar to the bottom bezel, plug it into the USB port and that’s it, you can control the screen with your fingers. It doesn’t add a capacitive layer, like on a phone. Instead, the bar projects a field of infrared light that recognizes the location of your finger.

No…just….no….
