I had the chance yesterday to have a play with the HTC Vive VR system. Although the experience is still a little restricted (the umbilical cord to the headset for one), the potential here is so clear.  Even the rudimentary games available now are so intuitive and tactile. 

In spite of the volume sales of Google Cardboard, I have been a sceptic on whether VR will make the mainstream for consumer applications. High price point, total occlusion and substantial hardware requirements are all major issues but what I experienced caused me to reconsider my view.
