Microsoft Surface Duo Phone / TBA
Long-rumored, the first mobile phone from Microsoft after Windows is not really a phone at all. Of course, it makes calls, but this is just one of the Surface Duo's abilities. This book-like machine has a pair of thin 5.6-inch displays extending to form a display layer of 8.3-inch. When the 360-degree hinge is twisted, it can be used as a tablet, as a mini-laptop, or as something completely different, so both screens face outwards. This runs Android and will be available for the 2020 holiday season instead of Windows 10X like its major sibling the Surface Neo.
