Microsoft demos Windows 10 apps on HoloLens, and it's stunning

Microsoft’s annual Build event, led by CEO Satya Nadella, waited until the end of Wednesday’s keynote to unveil the most stunning part of its presentation: HoloLens.
The company showed off how Windows 10 apps work seamlessly within what Microsoft calls the Windows Holographic platform. And it was impressive.
After Nadella handed the reins over to Microsoft vice president of operating systems, Joe Belfiore, to demo Windows 10, Belfiore then introduced Microsoft technical fellow Alex Kipman, who presented a series of HoloLens users on stage.
First, we got to see how the HoloLens handles an apartment layered in the holographic app panels. The customized room included holographic items, such as a virtual dog (name Fang), a robot and a holographic start menu on which he opened up a Skype call. The user then pinned the Skype call panel to a wall.
