Last year during Computex, ASUS introduced the ZenBook Pro 14 and 15, with a touchscreen in place of a regular touchpad. This year, it took the concept of a built-in second screen and went much further with it, unveiling new versions of the ZenBook with even larger second screens. Instead of just replacing the touchpad, the 14-inch second screen on the new ZenBook Pro Duo extend all the way across the device above the keyboard, acting as both an extension and companion to the main 4K OLED 15.6-inch display.

The touchpad-replacement on last year’s ZenBook Pros seemed like a novelty, with the bonus of giving you a small, extra screen for messaging apps, videos and simple utility apps like a calculator. The much larger size of the second screen on the ZenBook Pro Duo, however, enables many new possibilities. Both of its screens are touchscreens and moving apps between the windows with your finger takes a little bit of getting used to, but it is simple and intuitive (frequently-used apps can also be pinned).
