At present I have my own small business creating VR experiences, I've managed to do about Euro 80k in business in the last six months. I have three large clients and have probably personally ushered more that 2,000 people through the Oculus based experiences at trade shows. Perhaps 1 in 100 people "bug-out" of the experience within the first 30 seconds. One executive I work with won't put the Oculus on anymore to approve work, he instead gets colleagues to try it and gauges their opinion.
However, it's been a learning curve avoiding 100% nausea inducing experiences. Certain camera moves and experiments have made me so ill I had to sleep it off for a few hours. So in my opinion, it's not the display tech, it's up to the experience of the application developer to know what works - and what will make you seriously ill. It's a strange job actually, programming that will make you sick if you get it wrong. :-)
At present, the big problem as a developer with a business like my own is that we can't get headsets. There is no VAR program. I feel that Oculus & HTC doesn't take developers of business applications seriously, or at least, I don't have any contacts there.
I've been involved with VR since the VRML hype of the dot com boom and the technology has come so incredibly far - my sense it that it will continue to progress and become a new display technology that's pretty much on everyones desk.
