Finally got to try this. It was good, but technically very flawed for me where my friend was far more impressed. I couldn't get the thing in focus, and the adjustment to get it in focus was very crude. With no IPD adjustment, I couldn't centre on the screens. After some use I managed to relax into it and accept the blurriness and double vision, but it was far from a simulation of real life.
The tracking was absolutely perfect. 120 Hz felt perfectly responsive when moving one's head around. Played a few of the Playroom VR games and the 3D was pretty good. Played Skyrim VR expecting great things and IMO it was rubbish. The control scheme (dual Moves) was ridunkulous, turning with buttons on the right controller. I went straight for actually VR control and not weird teleporting which I found immediately far more disorientating, suddenly appearing somewhere else. Plus that changes the gameplay as you can teleport away from trouble instantly. The vague waving of weapons to hit enemies had no sense of control, like Wii waggle. Just thrash around with the sword until they died, without any sense of timing or Move type combat from the better Move games. And shooting arrows was impossible because everything was so blurry and low res, I couldn't see an arrow fly or hit.
The TV out idea also needs work, because showing a raw feed of a person's head movements looks like god-awful amateur-hour shaky cam. For the player who's inner ear is telling them how their head is tilted, everything looks properly aligned, but on the TV out it's all shaking and rotating around with the slightest head movement making it difficult to watch. It should be normalised to 'up' and shake-reduced like digital image stabilisation in a camera.
Apart from a little eye-strain, I didn't feel any negative side effects. It'd be nice to try VR with a decent display that can accommodate my outlier personal optics, but that'll probably be too expensive for mainstream devices.
