Several years ago I was friends with a guy who was so susceptible to motion-sickness that he couldn't even play the original DOOM game on an ordinary-sized monitor without becoming nauseous. I feel pretty sorry for him. I guess he'll never be able to experience VR comfortably. :-(
@pmulrich: It's really bad when the ad server is allowed to hold the content hostage for as long as it pleases ... and takes 2 minutes to deliver a "30 second" advertisement.
If you already have an Android or iOS smartphone then you can experience virtual reality for the cost of a few pieces of cardboard and two lenses: ~$25.00 or less. Just do a web search for "Google Cardboard".
