Steve Jobs thought that the NeXT was going to change the world. (For its time it was certainly revolutionary, but I'd call it too revolutionary for sufficient adoption.) Sergei Brin, Marc Andreessen, and John Doerr thought that Google Glass was going to change the world. Many smart people were quoted similarly on the Segway. Ditto on 90's VR or any number of other interesting ideas that turned out to have some flaw or not deliver sufficient value.

I have used neither Glass nor the latest generation of VR. Which I'm ok with. If I did, I might or might not think them cool, but that's irrelevant. I'm not in any of the plausible market niches for early-stage VR, so my personal experience won't say anything useful. The kind of evidence I'm asking for here is not whether somebody thinks something is amazing. It is whether they are finding it useful enough on a day-to-day basis that they are paying for it and re-paying for it.

If they are, that's great. And if not, well, maybe we just aren't there yet. It can take time for technologies to find their feet. But given that I'm getting a host of replies with anything but what I'm looking for, that seems telling to me.
