Use for mainly home and office makes it niche? That’s where people spend probably 80% of their lives. It is niche, but not because of that. It’s mainly because of price, and then battery life and comfort.
And I mean niche compared to a laptop, or more accurately an iPad/external monitors, because that’s what it shares functionality with so that’s what it should be compared to.
I’m not sure why you’re comparing it to an iPhone. It’s a totally different animal. No way any headset in any foreseeable would be as ubiquitous as a phone. It would have to be AR (not MR) glasses (not headset)—thin, light, affordable, good battery life. And even then it would require a phone for tether, so it would still probably be less ubiquitous.
I said it’s as isolating as a scuba mask, and you again said it’s isolating, so does that mean you disagree with the comparison, or you think a scuba mask is also isolating (ie. blocks your senses and blocks others from seeing you)? Because that might be where we disagree (tentatively, I’ll make up my final mind when I use it). From what I’ve seen with EyeSight, it essentially looks like a scuba mask from the outside, but with slightly off perspective on the eyes—but otherwise all the information is present, anything else can theoretically be gotten used to. From the inside, it might actually have better field of vision than a scuba mask, not sure.
And if you mean it’s isolating because the user probably has a some app(s)/window(s) open, then it’s just as isolating as a monitor, phone, book, or any personal object that you’re looking at, which is a necessity of life.
