Tried it. It was okay, felt very futuristic. But ultimately there weren’t really any benefits over just using a multi monitor setup that could justify the cost. I thought it’d be nice to have something I could also use for watching movies, but when I watch movies I almost always watch them with my wife, and much prefer that.
Daily driver no, but after the somewhat recent ultrawide monitor update, it is absolutely viable for travel. It's nice not to be constrained by a 14" monitor while on the road, and it's perfectly usable for a couple hours of work (especially if you take the surround seal off and use one of the head strap mounts that take all the pressure off your face).
I tried it, and it works alright. But it's not very comfortable to keep it on while eating/drinking, and you can't wear the thing in public without looking ridiculous.
Personally I found my existing dual-monitor setup to be more ergonomic.
