The current model has it's problems, but I really think this is the start of a new major product line for Apple. This isn't going to be relegated to only the rich forever. There are a few problems to over come. It needs to be lighter, it needs to be cheaper, and it needs better battery life. All of those should be somewhat resolved in the next 10 years. When it does, I think the market will explode.
The big selling point? TV. I know over the last few years I have kind of fought with my mom because she is hurting her viewing experience for the sake of aesthetics. The TV is mounted, but has a cabinet in front of it. It is loaded with tons of seasonal decorations. The reason? She can't stand the site of a cord. So instead, she has figures tall enough to cover part of the screen blocking the view of the TV, all so the cords can be hidden behind the figures. So yes, she loses part of the viewing area, and the remote doesn't work unless you get up and go to the side of the TV so the IR sensor isn't blocked, but it LOOKS better!!
The thing is, she isn't alone. I bought a TV last year. During the time researching it, I would see similar opinions to my mom's. Peopel would post pictures of their TV setup, asking if the size was OK, or if it should be higher, and the responses would be similar, telling the person to run cables through the wall, or get smaller stands or other complaints. It made me realize that many people care about those kind of things, and it will drive their purchase decisions.
All the Apple Vision Pro has to do is show them that you can have a TV, with no bezel, make it any size and position you want, you get rid of glare from the sun, and it has no visible cables. That alone is enough for people to want to buy it. It isn't there today, but it will get there in the somewhat near future.
I would do the same thing I do with rare, single use items in video games (Think the Master Ball). I would save it indefinitely in case there is a time that I really need it in the future. I would die having never used it.
