This Gadget Gives Your MacBook Air A Touchscreen

After using a Surface Laptop for a week last month, I caught myself reflexively reaching to tap the screen on my MacBook Air. Touchscreens are conspicuously absent from Apple's MacBooks, whereas Windows PC-makers have been offering displays that respond to pats and swipes for several years.

That's exactly what Swedish designer Neonode hopes to change with its AirBar, a $99 gadget that plugs into your 13-inch MacBook Air and makes the screen touch-responsive.
