To your first point, the difference is that I need a phone and PC for work. Maybe eventually owning a painting company will require me to also own a VR headset, but I don't see that being the case in the next 5-10 years. Maybe a person can convince themselves that they are "traveling" instead of just wearing a VR headset, but I can't imagine the sad, lonely existence of taking a week off work to spend a week in Tokyo in VR. VR isn't and will never be replacement for going out and exploring the world.
I want the premium version, and I want it for less than $200.
As to your other point, there are no "conventions" around me where I would be able to try it on, and even still it just seems like it's pretty gross even with a disposable face mask. Maybe I could be convinced if I were like the second person to use it out of the box, but my fiancee wouldn't. Best Buy, at this point, is not a store that most people ever go into. You would need kiosks everywhere. Like public sidewalks, parks, and other non-retail locations since let's be honest retail is going to be changing substantially in the next 5-10 years.
Like I say, I want to be convinced, but the only thing that's going to convince me is trying it, (and we've discussed the restrictions around that), and the price point needing to be substantially lower.
