I would completely distinguish between the b2B and the B2C space. Mobile Tech, Highend graphics, immersive gameplay and CGI are but 4 areas that show the way of how this might work.
Remember that Microsoft's PocketPC platform was quite successful in the late 1990s early 2000's in enabling things like industrial warehouse scanners, UPS package delivery tracking etc. In some ways that success hampered MSFT in building a better consumer device, and Apple capitalized on all the tech that MSFT and others in the B2B space had pushed through before launching the iPhone.
High end and immersive graphics came out of Silicon Graphics (SGI) and the graphics language OpenGL came out of their proprietary IRIS GL. These graphics were originally being used in high end B2B scenarios (Tectronix, DEC engineering wkstas, Evans & Sutherland and Singer Link flight simulations, SGI's immersive CAVEs). this then moved to more "affordable" SUN workstations used still in B2B for CAD design... and eventually the push into making PCs be "workstation capable" some 15 years ago.
And from there you saw some early very specific B2C scenarios. there were "LAN Gaming" shops that opened up all over the place in the early 2000s. These were places where very expensive gaming machines ($4k each) would get connected via expensive "high speed" lans (100 mbit Ethernet)
And you ran a limited number of games.. And in 3-4 years this technology had commoditized enough that my sons and their friends all pitched in to buy an 8 port hub so that they could do their own "LAN Parties"
In this current round, I see Vive positioned the most strongly to start entering the B2C space, though FB with Occulus is going to be interesting as well. Why? Because Vive has Valve behind it, ie it has the potential for content: Portal 3D, Half Life 3D the Reboot, etc. And those would be aimed at that "LAN Party Play"
I don't count out FB because of its extremely deep pockets and we will see what the announcements at F8 bring us.
But these are going to be fairly limited in B2C application for a while.
HoloLens - precisely because it is AR, and because it IS initially tethered, is likely to do what Glass was hyped to do. You won't get "HoloHoles" as you did with Glass because they ARE tethered. So you will see them used in a variety of things that are high end... things like say the high end Jaguar (MSFT has a strong alliance with FORD) having a HoloLens that plugs into the onboard systems and does navigation, as well as driver safety.
and I could see setting up a "HOLOLens Deck Gaming" shop:
rent out a warehouse - like an less used Indoor soccer arena or such, have backpacks that are carrying an AlienWare 15 laptop with an external Batter http://lifehacker.com/five-best-external-battery-packs-509802431
a tethered HoloLens or Vive (Vive will be tethered according to everyone who I've heard discussing it who saw the device in person) and an AR marked "weapon".
You can now run an immersive MIRPG (Multiplayer Immersive RPG). Imagine doing the HalfLife 2, but in VR - where the immersive environment is with you and you and up to 10 friends can run through an interactive session. Or better yet, do a variant that intermixes Laser Tag/paintball into the mix. where one side is the protagonist in HalfLife, and the other side is some nefarious secret organization who has a goal hostile to your team... or just immersive Dungeons and Dragons.
Now this will be limited in its market appeal but it will have some. and that in turn will drive the experience more and more into the consumer space
and of course the ever present driver of virtual sex. there already are VR porn sites up (you can search for them on your own if you would like)
but this is an evolutionary process because the hardware is currently still quite cumbersome. HoloLens is the closest to being "daily wear"
