I don't have mine yet but was lucky enough to have a colleague bring his in. The first demo of walking around a kitchen was fine, but the carnival ride demo induced incredible nausea. I had to remove the DK2 after just a minute or two. It's an hour later and I still feel pretty sick.
When showing off your DK2 to people, try to choose demos that will not induce nausea as it will leave a pretty bad taste in their mouth about VR technology.
