The main selling point of the Surface Duo is its multitasking competence powered by Android 10 and running a customized interface that Microsoft believes will be a game-changer for productivity on the go. Microsoft has reworked its Office and OneDrive Android apps specifically for the Duo and third parties like Amazon and its Kindle app are also jumping on board to take full advantage of the hardware.

There’s also a single 11MP camera with F/2.0 aperture which sits on top of the right display alongside the LED flash. Microsoft is touting a “super zoom” feature with 7x zoom which is entirely digital. The camera is also capable of recording 4K videos at up to 60fps and comes with EIS.

The Duo will also work with all existing Android apps and comes with its own algorithms which can predict where you’d like to view content and how to open new apps side by side.

The 360-degree hinge offers versatile modes and use cases and both screens come with support for Microsoft’s Surface pens. The Duo is also pretty slim, measuring just 9.6 mm when folded. While rather small, the 3,577mAh battery is rated at 15.5 hours of local video playback and up to 27 hours of talk time. The Duo comes with an 18W power adapter in the box.
