Without a doubt, the biggest surprise from today's Windows 10 keynote at Microsoft's Redmond campus was the outfit unveiling its HoloLens headset. Dubbed as the "first fully untethered, holographic computer" the device and its capabilities looked pretty neat -- if a little fantastical -- onstage when Alex Kipman showed it off. But for all his talk about breaking down the walls between technology and people, there are a surprising amount of them around exactly what the device is packing under the hood. We asked every person at the event that we could (developers, public relations folks, engineers) about the specs of the dev kit we tried, and were shot down at every turn. No one would give a single, concrete detail. So let's break down what was said during the stage demo (embedded below) and what Microsoft has released via the HoloLens website instead, shall we?
