I guess you could include it in 'price and equipment' but for me I simply don't have space in my apartment to do any of the interesting things with VR (eg I really enjoyed SuperHot VR), and it doesn't seem much of an improvement if I'm just sitting in my chair with it. Floor space is extremely expensive in almost every big Western city at the moment.

> VR headsets are very hard on the human brain, since they confuse our multiple range sensing systems.

I disagree. They are hard on brains of some humans, mainly due to motion sickness. But that happens only when there is artificial movement involved - when user's movement doesn't match camera movement.

And it really depends on the person, some are more susceptible to that, some are less. I also think some resilience to that effect can be trained with practice.

Then there's the style of artificial movement provided by software. I've seen several solutions which make it more bearable - generally those involve some degree of physical activity beyond just pressing a button.

Adjustment of focal plane seems like a rare problem; it's honestly the first time I hear it mentioned as an issue which is "very hard on the human brain". Usually it's all about motion sickness.

> but I have yet to see any usage that would justify spending spending as much one one as I did my TV

For me, it's about activity it provides as much as it is about immersion. I wanted to reduce my time sitting idly, and VR lets me do just that without abandoning gaming at all.
