You are completely ignoring psychological comfort. Imagine how long a typical couch potato would be willing to watch an idiot box if they had to stand up to do it or if they had to continually twist and flex their neck or it caused nausea. I write this from a lazy boy rocker recliner with a customised over bed table to hold my desktop, in the lounge with a nice view out the window and a big screen TV. Yeah, comfort counts and VR doesn't really cut it, in those stakes but hell, I don't care either way. You know what, lets run a test, grab some people and make the use VR 8 hours a day for a week and see what they feel like, hmm, OK? (now ramp that up to a month or how about 8 hours at work and 4 hours at home).
Simple immersion 3D video and sound are going to be difficult enough to make comfortable with extended use, without demanding people will never be allowed to rest their heads or even entire body (stresses building up in the neck, affects the persons entire physiology).
Sure likely to be fun with limited use but extended use will be hugely problematic. Simple immersion systems with no motion just cheaply extending the usability of a smart phone, turning the small screen into a very big screen, fairly cheaply with a huge improvement in usability but still likely to have limitations on extended use due to discomfort.
Seriously knuckle head, you can't seriously expect anyone could possibly believe people would accept TV if they had to wear a face mask to watch it and not be lounging about with their family, in the lounge room munching, oh yeah forget that bit huh, drinks and munchies, oh my, what will you do (hmm grope around making a mess or stop every time you had a thirst or hunger, oh yeah, that will go down well with the typical gamer). Let alone getting stoned whilst drinking and playing VR, more than the screen will be technicolor http://www.urbandictionary.com....
