Surprised to hear you say that. When I got my first oculus, I was struck by how much better it was for nongaming applications than gaming ones. Things like Giants of the Solar System, or tours around historical sites and events. Things like providing visualisation of designs that are yet to be built. Taking a small object and examining it closely in 3d at different scales. Education, training.

I actually think the gaming features of the current crop could end up being a niche use.

VR is not inherently anti-social. Applications like AltspaceVR are very social. Also, I've had groups of people at my home to try out the Vive while projecting the headset content to a wall, and it's always a very inclusive and social experience where HMD wearer and audience participate alike.

In terms of eyestrain, I think you may want to check the IPD setting on your headset (if you own one that supports it), since due to being focused at a farther distance than regular monitors, it should be (and is for me) quite a bit less straining on the eyes.

Resolution is still sub-par for screen replacement though.

In a few generations that could be alieviated though
