This is like saying "for the price of car, you could buy 20,000 bicycles". While that's true, I'm not going to ride my bike from Texas to Disneyland.
I would not suggest getting all of them anyway. It’s just to observe that the opportunity cost of disappearing inside an expensive virtual device is matched by the financial cost.
One gadget is the equivalent of the outlay of an entire well-funded hobby that might broaden your horizons.
One can choose to go into a consumption mode with an AVP or be active and move oneself outside through a real 3d space, the landscape we live in. What is better for the health? Mental and physical.
I would guess that the AVP is a temporary device to get 'us' into a future with different hardware for spacial computing. Something for the developers and early adopters -> the actual mass market(s) then will look differently.
The current trend in tech is that the stuff&servives we use is becoming more and more a mental burden to us: information overload, distraction, noise, manipulation, control, ... the future that has been warned about is now here and a lot of people can't handle it.
The AVP is the 3d version of it. It has potential, but there are a lot of warning signs on its effects on society. People get more and more disconnected from the reality. We'll already see lots of people staring at screens, instead of interacting with their immediate surroundings. This will get worse...
