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.
