Eh...I guess I've gotten good at just paying attention to the screen and blocking out the world around me. The question of it looking like a 100 foot tall screen that's 200 feet away or a 13 " monitor that's two feet away is a non-issue, it takes the same FOV to your eyes. But sure, maybe at a much cheaper price point having the world outside the screen blocked is cool.
It's not VR, but I remember Sony used to sell movie glasses that projected a largescreen TV in front of your eyes. It wasn't VR - the monitor was always directly in front of you. They actually worked really well, and did exactly what you would have wanted for a movie or monitor on an airplane. They were relatively small (much smaller than VR goggles) and I seem to recall they cost like $800 in the early 2000s. Tech worked great but nobody bought it, AFAIK nobody currently sells anything like that.
