I Finally Believe in Microsoft's Mixed Reality Vision

For years, Microsoft has been talking about its dream of mixed reality -- the idea that AR and VR headsets can work together in harmony across virtual and physical environments. But until now, it really has just been talk. At its Build developer conference this week, I finally saw a mixed reality demo that made Microsoft's ambitious vision seem achievable. It was more than just shared VR -- something we've seen plenty of already -- it was a group experience that brought together HoloLens and Acer's virtual-reality headsets in intriguing ways.
