I think that VR does have a lot of good applications, but for the most part I don't feel it is being used to it's full potential. There are some instances where doctors have been able to get views of organs that they normally wouldn't . This has led to less invasive techniques to remove tumors etc. I am glad that the 3D fad has died and we are seeing more of a move towards VR though. The 3D TV's seemed like such a waste of technology to me. I felt that our research would be much better placed towards holograms or now VR. My vision of the future is holodecks like on Star Trek where you get a combination of the two!
