The mixed-reality "holographic" headset and a half-dozen apps arrive on March 30.
More than a year after it was announced, Microsoft's augmented-reality headset, HoloLens, is about to get more real. Starting today, the company, which began letting developers register their interest in buying $3,000 HoloLens developer kits last October, is allowing them to place actual preorders. It says it will begin shipping HoloLens Development Edition on March 30, thereby hitting its goal of doing so in the first quarter of 2016.
