It’s been six days now of solid work on it. Seems to be sticking.
The improved ergonomics include greater physical flexibility and comfort, as well as the visual benefits.
Physically, I am now moving as I feel inspired, between my desk, a couch, bed, and an egg shaped chair with a foot rest. I only need a keyboard/trackpad on my lap, and my MacBook nearby.
The visual benefits turning your whole mental visual space (your fovea, peripheral vision, and head turning field of view) into a visual desk of any number of items is fantastic.
Being able to make my main screen as large as a wall is nice. Seems like for some work, a smaller screen feels better, for other work a very large or wide screen helps.
Downsides:
1. Needing the Mac at all. Would love it if Apple shipped Xcode and Terminal for the Vision. For now I move around and would travel with both.
2. That first one would solve this. But for now only one Mac screen
3. The Vision screens respond to both keyboard/track pad and look/pinch, the Mac screen only responds to the former. You get used to doing both.
