I don't know about that ObamasBFF. I'm a regular mobile VR user and while the performance of the Gear VR, Cardboard, and Daydream (I've tried them all) is decidedly low end, most of the people I show it to are far more ooh and ah than apathetic. Once I say that this is the low end of the capability their interest in it improves. I'd say the Gear VR has had the biggest impact on friends I've shown it to because all of them that had Gear VR ready phones went and got a Gear VR. Of the ones that didn't have Samsung phones, most went for one of those plastic $30 headsets from Amazon. It is an easily enjoyably medium that is just begging for more content. Something between a phone experience and a Vive/Rift experience is desperately needed to hook more people and grow the platform. If this Windows Mixed Reality system can do that, then VR will be just fine. It sounds like these headsets have 90% of the features and functionality of the high end headsets, at least. If these can't hook more people then the 2nd gen gaming headsets (whenever those come out) are our last real shot at getting VR off the ground this decade.
In your example all people really need is context. If that is all that is holding people back, things are going to turn our just fine for VR.
