Fundamentally, these companies have to show how their product is a) unique and b) useful in a way that differentiates the headset from using a laptop or a tablet or a smartphone. I think all of them are great at marketing point a but seriously struggle with point b. Getting widespread adoption, in any way, requires moving beyond novelty factor and into serious impact on how people work or go about their lives. Apple seems to be really focusing on domestic, 'casual' applications, or 'knowledge work' style arrangements, like meetings or co-operative creative work. I don't think people will find much benefit in that outside of their normal desktop workstations. AR in warehouse or construction or more labour intensive situations or (unfortunately) military applications is actually where I think something like these headsets could be more successful. Cheaper devices do have an advantage in that respect, so long as the tech matches the user need. To summarize my point, I think we're still a good decade or more away from the point when these headsets reach anything near moderate adoption. At some point the cheap devices, the amazing tech, and the clear use-case will converge; but I don't think we're there yet.
