One thing which I don't get why people don't seem to get is long term (and perhaps with this release from Apple) headsets should be replacing tv's for at least a substantial amount of viewing. For example I have a fairly high end 4k projector setup but in an apartment with limits on light control. Even with a dedicated room and $3k allocated to a projector and a screen and high enough resolution (which i'm expecting this headset will be) headset should be able to blow away in terms of perfect light control and thus black levels (assuming OLED) and resolution. And then the ability to not just render a normal home scale theater but trivially an IMAX style if you so choose. Further in a home environment I can see still having a small theater room literally just for the audio equipment which will beat out headphones obviously for a theatre experience but replacing the projector and screen and not requiring as large of a room.
Really I think social home sports viewing is the only situation for an argument of physical tv viewing and the comfort level (which i'm expecting apple to have improved on here similar to what Bigscreen is doing).
People talk about killer apps for VR and i'm like this is clearly it, we have just been hardware limited so far. People very comfortably spend $1-3k+ on decent TV's and that is just a tiny aspect of what VR can do.
