I got a DK1 a few years back and was ridiculously excited to try it out. I had blocked out the whole weekend to mess with it. I tried it for under an hour, took it off, and didn't use it again for a week. It made me nauseous and gave a killer headache. My wife and brother had similar experiences -- both expected to be thrilled and have difficulty putting it down, but both ended up keeping their distance after the initial experience.
I haven't tried any other VR devices yet (skipped the DK2), but I look forward to demoing the CV1 at some point. Since Linux support has been killed, it will probably be a while, whenever I get around to building the separate free-standing Windows machine I've been intending to get for the last year or so (with dual-boot, I find I boot up Windows once a year, or twice if MS is lucky that year; I just have too much stuff running on my primary workstation to let it go powered off for very long).
