Microsoft is returning to making phones this week, as part of an ambitious project to usher in a new era of dual-screen and folding devices. The company has spent around six years developing Surface Duo, its Android-powered device that folds out to be a phone or a miniature tablet. It’s taken Microsoft years to get the hardware and software right, but the company firmly believes now is the ideal time for something new. When it goes on sale tomorrow, we’ll see if the company got it right.
