I own a DK1, and agree with you on a lot of these points.
I would add that while first-person shooters universally made me sick to my stomach within about 5 minutes, flight sims generally never did. My guess is that being seated in a virtual cockpit and flying around seems a lot less wrong to my vestibular system.
Unfortunately, the flight/space sim market is a rather small one within gaming as a whole. Though it does tend to be one full of people generally more willing to buy dedicated sim hardware than most.
The DK1 is just awful in comparison to the DK2, though. Positional tracking and reduced latency of the DK2 improve the nausea situation a whole lot. I haven't had a chance to try the CV1 yet, but it's supposed to be an equally big jump.
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).
