Microsoft is building support for holographic displays into Windows 10, so it only makes sense that the company would make one of those displays, wouldn't it? Meet HoloLens, an official headset with see-through lenses that merges digital content with the physical. It includes spatial sound so that you can hear things happening behind you in the virtual world, and it even has a dedicated Holographic Processing Unit (HPU) to make sure everything works smoothly. The company is shy about just when it'll start selling HoloLens, but it should be available "in the Windows 10 time frame."
