sorry you got the wrong impression. Microsoft Windows 10 is supposed to be used in the IoT devices, as well as HoloLens, Surface, etc.... If you looked at the Vinci 2 you would see an entire computer system, not just a set of headphones. The Surface Headphones could be a part of an augmented reality system to come. The second part would be glasses like HoloLens or something like google glass. The Vinci system uses some small displays on the outside of the neck band. If the Surface headphones are planned as an entire computer system it would use WIFI as the Vinci system does. You assumed I was put off. Wrong. I'm excited about systems that are coming. Satya said that when Microsoft does another phone, it won't look like a phone. Could this system evolve into something he was hinting at?
