I managed to try out Microsoft's HoloLens 2 at MS Build this year in Seattle. My impressions were that it's a very cool, very impressive prototype. FOV is still quite low, although I hear it's significantly improved from v1. Framerate felt too low for real-world stuff; as you were alluding to, our brains are used to screens operating at 60fps, but there's something about putting the screen right up next to your eyeballs and adding tracking (whether VR or AR) that kills that illusion and mandates at least 90fps, and very smooth. I'm not surprised by the reports of people getting motion sick. Having said that, the fundamental interactions are very cool. I had slight difficulty figuring out where the tracking was actually registering (e.g., how far do I have to move my finger to 'tap' a button), but once I figured that out it worked just like you expected it to.
