For me the Vision Pro is my main machine now (supported by a MacBook Pro). And I absolutely love it.
Which is saying something. My second most ergonomic situation is a 120" screen with two 55" screens tilting in from both sides (both in portrait, so all 3 screen verticals line up). All wall mounted. I started wall mounting to get screens off my desk, at which point it was clear bigger was always better.
But for the Vision it took many rounds of trying third party head gear, and customization, before I could wear it comfortably for unlimited time. I just kept trying things until I got there.
I am an obsessive optimist when it comes to ergonomics. Once the Vision is ergonomic for one's head, then it becomes a super ergonomic solution over all. The screen can be wherever you need it for best neck, back and body posture, whether at a desk, couch, (non-driving) car seat, or in bed. And a very wide screen beats any screen patchwork. Although I would like the Vision even more if I could have more than one Mac driven screen when I wanted to. (Recommend expansion batteries that clip on the original, and round magnetic USB-C cable adapters, for more spontaneous mobility.)
I like the standard Apple straps in a pinch. But my face needs a serious break from the weight they distribute on it, every 30-120 minutes.
