Yes because I feel the mode of interface is entirely different.
Looking around with your face and using you legs to walk (with a correct treadmill setup) will be much better for human computer interaction in my opinion.
I love my vive but I too am a little skeptical? It is an entirely different experience and it's cool. I am just not yet convinced that in the long term the interface will be as productive. Now glasses size true AR that is light weight high FOV/Res would be a game changer.
