I think this type of AR / holographic technology has many, many more potential real-world applications than VR. With VR, you're shutting yourself off from the outside world. Here, you're enhancing the outside world with technology. You still get to interact with others. Using HoloLens doesn't stop you from doing almost anything.
What I'm curious to find out is whether HoloLens will run into the same core problem as Glass. People are afraid of people wearing Glass. They're scared that they're being filmed, or worse. Unless HoloLens can avoid making you stand out - by looking like regular glasses, or even contact lenses - I'd guess that HoloLens will end up suffering the same fate as Glass.
