Pretty much this. Wii and Kinect comparisons couldn't be further from the experience and would only be made by people who haven't tried it. It's so different that drawing a comparison defeats the purpose entirely.
That's how I can tell you haven't tried it.
I'm not expecting to mountain bike or be a football allstar in VR. My point was that a little movement during an enjoyable activity is not much to ask and generalizing that the bulk of people are too "lazy" to want to do it is a disservice. VR makes you
want to move around and interact with the world. All of the stories of people with DK2s reaching down to pick up a virtual object aren't a coincidence. No one is saying you have to run marathons in VR, but moving around in a space naturally is huge and cannot be overstated. Having virtual hands is absolutely mind blowing and makes the world that much closer to real since you can affect it in a way that is natural to your brain. Once it's been tried the idea of a gamepad is almost offensive and seems absurd.
