I have never seen anyone wear a head mounted display anywhere, period. Not at work (finance, Chicago), commuting or travelling, at home, etc. Are you saying this is actually a thing?
They are used in niche applications. All in a somewhat similar way, in my opinion: precision technical work. Where you need free movement of your head but also need urgent real-time updates, or a diagram or secondary view, of what you're working on. Fighter pilots, surgeons, underwater divers working on complex machinery. I've always figured they will stay largely restricted to those niches. But cost coming down might see new applications.
I've seen one used at work for R&D demo purposes, but aside from that I don't think I've ever noticed anyone using one while out and about (Cincinnati, OH). Certainly never in transit or on an airplane.
I’ve seen one, a couple of days after the Apple keynote, sitting in the cafeteria at work. I’m not sure whether I was more susceptible to noticing it thanks to the AVP.
