The Surface Duo 2 is not a run-of-the-mill device and it’s clearly not meant for everybody. It’s aimed squarely at people who believe that focusing on one thing at a time is wasteful and like to use their devices to their maximum potential.
The 360 hinge can keep the device in any position you like. So, for instance, you can fold one display all the way back and use the Duo 2 like a conventional phone, use it like a tablet, use one app on two screens to do different things, or use the tent position to play games with your Bluetooth controller.
Another trick that the Duo 2 has up its sleeve is that the inside edges are slightly curved, so you can still see a portion of the screen when the device is folded shut. Microsoft calls this area the Glance Bar, so even though there is no external screen, you can see heads-up info like the time, battery percentage, messages, and incoming calls without needing to unfold the device.
The Duo 2 is powered by the Snapdragon 888 chip which is sufficiently fast and provides solid performance. It has a triple rear camera array and a selfie camera and they take detailed pictures in most lighting conditions.
