Never underestimate the allure of status symbols. For the longest time I thought the same thing of the iPhone. Why would people spend so much when they can get Android for considerably cheaper ? It's the status stupid. Of course, now they are ubiquitious and no longer really much of a status symbol, but if you go back a decade, you'll know what I'm talking about. The same will happen with VR as the tech improves and prices drop a bit.
They aren't that ubiquitous in the UK/Europe or Asia. I've never used an iPhone. I'm not sure of the market share figures but I'd guess it's about 50/50. Similarly with Mac laptops you get the impression that everyone buys apple, but it's really not the case and it's probably more like 75% windows at a guess.
