I've gone on mediocre ski runs, so I'll accept the nitpick. Here's another; My hunch is that the simulations will involve standing, leaning, hopping, etc, so the runs probably won't happen on a sofa.

I've certainly been amazed by the paraplegics I've seen on the slopes. I still think that more people will be able to afford the VR gear than will be able to afford traveling to slopes, buying lift tickets, real gear, $10 sandwiches and $3 apples.
