No, I have not tried it, but I'm not comparing the tech experience, I'm comparing the potential market demand. Like I said, the development should continue because it's usefulness is likely greater outside of consumer electronics, such as the medical field.
I use a flashlight daily in my line of work. A head-light would be optimal on paper for me to use and I own several, yet I very rarely use them. I hate wearing shit on my head. I use ear canal headphones, a behind the neck headset, a neoprene mask for cold days, etc. I also hate being tethered with cables. These two issues will likely sway me from any of the current/near future VR tech regardless how awesome it is.
I get that...but really, you could make that same argument for PC gaming in general. How much of the "mass market" even has a PC these days? That's honestly a fine line I think VR has to walk. Even WITHIN the niche they're already in they have to be careful.
The second Rift development kit (DK2) for example needs a PC that can push a 3D image at 1080p and 75fps. The consumer version is looking at 1440p and 90fps (for anyone wondering "why the high fps?", that's generally what it takes for the head tracking to feel natural...and if you can't hit that, you start feeling sick)
So, while we've finally reached the point where consumer VR is legitimately possible, it's going to very quickly outpace what most people can do with their PC. So, like you said, a lot of its success could very well come from the science and medicine fields. It's definitely not just going to be something that "Joe Console" picks up, plugs in, and is whisked away to magical lands.
Granted, that's what Morpheus is trying to be...but considering the horsepower that the beta Rift needs for it to function...and it STILL has problems, I'll be shocked if Sony pulls off an enjoyable experience that the PS4 hardware can handle. But from a personal standpoint, I don't care because I understand computers and I know what is needed to make it awesome, lol.
And if it flops, I at least have my hardware and enough community developed games/experiences to keep me entertained. That's honestly one of the reasons I got in on the early Rifts. If they somehow

it up, I didn't want to miss out on seeing what it was like.
