I think you're missing my point. I want it. I'm the early adopter. I don't want Google Cardboard, I want HTC Vive. But the price of the full setup right now is going through the roof. I'd be interested to see how much people are spending on average.
This does mean that early adopters tend to have more discretionary income. It is unfortunate, but unavoidable.
Or let put it this way: if I'm not an early adopter, then their early adopters are too few to make VR a success.
