Touchscreen laptops have been around for a while now. Not ready to get rid of your current laptop? Thanks to AirBar, you can turn your notebook into a touchscreen device. This particular version works on 13.3″ MacBook Air laptops.
To get started, simply attach the unit with magnets and plug it into a USB port. Once done, you will be able to use your fingers to touch objects, draw, and do a whole lot more on your laptop.
