Usage is a big thing, not everyone wants to play Elite which is 80% of the use mine gets. Occasionally I play the gun slinger but only the shooting gallery as I don't have the area to duck and dive about in behind my desk even if I wheel the chair away. Dirt Rally is utterly impressive, but possibly because my graphics card is under spec tends to give me motion sickness so I can only play half an hour at a time.
Interesting that the minimum GPU spec for the Microsoft headset standard is really low to allow laptop use, I wonder what they expect people to run with that.
The absolute cost isn't that high, many people lose more than the cost of a headset in depreciation of their car every single month. The difference there is that new cars, iPhones and flat screen TVs are status symbols to many, an HMD just isn't. That could change if everyone is on some sort of VRbook social media.
That "research" puzzles me though. That seemed a pretty large percentage adoption for a new consumer technology based entirely off PS4 VR numbers where the possible audience is just percentage of PS4 owning households *not* percentage of adults.
Personally I wish I could find a game that my wife enjoyed playing in VR and I would get her a headset. You put that thing on, and you shut yourself off from the world, and you look a bit of a dick to anyone watching
