I really like the idea, and I think that VR is our future! But the price for VR devices is still quite high, not all users are ready for such a waste!
Price of VR devices will be constantly decreasing and whole technology will be much cheaper and easy to obtain
Just think of Google's cardboard goggles used with a smartphone: cheapest solution ever!
VR cardboard is the cheapest solution
Cheapest is not mean it is best.
I would want the highest reality feeling and best resolution. So don't sure the cheapest option will give that to me.
For me the future of VR is total immersion. For example like in the anime Sword Art Online. And I hope that soon such technology will be developed and available to everyone.
And this company is making steps in that direction!
