My cardboad kit is on the way! can't wait to try it out and decide for myself! (I may have to upgrade my phone now)...
However, he may be partially right, VR may be good for simpler, short, yet intense experiences or meditation like software... the common thing people who played around with it a lot seems to say is that they would not use these headsets for long periods of time, or that it's so different than a "regular" game that they do not see how it would integrate...
My opinion, with only about 5 minutes of use of an Oculus rift model 1 is that if you give me a regular controller and the head tracking is used to give me some partial control over the camera in a regular game I will LOVE it, imagine being INSIDE a car and being able to look around naturally while you drive, it look around in an FPS while walking(all other controls being adjusted to this).
