Part of the magic of VR is the immersion. AR doesn't appeal to me, it seems more of a gimmick.
I don't see VR providing a whole lot outside the area of entertainment. How often do you want to be completely removed from the physical world on a regular basis. Even when you do want immersion a good story or a game with good mechanics is far more important in entertainment than the medium it's delivered though. This is the reason people still read books, why retro video games are still played, and why 3D continually fails. A high tech medium, doesn't improve bad entertainment, but great entertainment can be delivered though a low tech medium. I'm not saying VR has no value, but I don't see it being some giant revolution.
On the flip side, AR doesn't provide immersion, but rather enhances the world around you. AR allows pretty much any information you get from your phone or computer currently to be instantly hands free and always available. If I told you I had a pill that allowed you to remember 20% more than you currently do, I can't think of many industries that wouldn't be improved by giving that to every employee. Once headsets become light enough and cheap enough, that's what AR provides. Instant access to relevant information without diverting focus.
VR seems to me like an extension of 3D technology, AR seems like an extension of the smartphone.
