In response to the OP, I just don't see VR being a big thing as long as I am forced to wear something. That is one of the major reasons why 3D TVs haven't taken off.
This is radically diffrent technology then a 3D tv, your not just staring at one spot, you can move your head freely, look around and into the world from any perspective you want. it's much more about immersion then some added depth.
From my personal perspective, I'm still a 2D game fan. What benefits would I get playing, say Mario, with a VR headset? What about surfing the web? This site certainly wouldn't benefit. Most wouldn't.
It's a niche and a very specific one at that.
really, mario of all choices?! of course not all game genre's are going to be a perfect fit for VR, as for we browsing, i could see virtual lobby's, and a new way to interact with the web could be made with VR(i think their are actually a couple projects which are working on this even now) there are even some virtual chat room apps that exist which give you an avatar to play around with while talking to other people.
and lastly, why does everything have to benefit from the tech for it to be useful? I am seriously dumbfounded at the people that say it's just a waste of time, and has no benefits to gaming whatsoever.
