I would have to say that VR for the time being is a fad. Not so much with consumers but with the tech companies, they all see an oppurtunity to make money on something that may fizzle out in the eyes of the consumer. I can see many uses for this tech beyond gaming/entertainment which seems to be where all the focus is at at the moment for most of these companies. I can see this being used in exploration via rovers/uav's, engineering, medical, forensics, and defense applications; and I would think that it's already used in some of these fields to some degree.
It is definitely interesting technology, but it is still even after all these years still in its infancy...well no it's past that stage, lets say in it's teens, it's ever changing, with new developments being made every week. I am excited to see where this tech goes.
