Microsoft has probably unveiled the most exciting/innovative technology of this century so far: HoloLens. It is an augmented reality (AR) goggles that, unlike VR, projects images on top of what you see.
The possibilities are limitless. You can have Skype, Netflix or even a browser positioned on air or your wall. You can see other people virtually interacting with your reality. Create 3D objects easily.
HoloLens is a standalone unit with a CPU, GPU and HPU (Holographic Processing Unit). Microsoft has not released details about battery life and/or if there will be a wired version available.
Windows 10 will have built-in API for holographic computing (any app can utilize this).
Technically speaking, AR is a superset of VR and it is possible that with slight modification/improvement, HoloLens can also function as a complete VR solution. With no lag (as demonstrated to reporters yesterday) and precise eye-tracking, it can arguably be a better VR solution than Oculus.
JPL (aka NASA) is using this already in their Curiosity project so scientists can explore Mars as if they are walking there.
