Even the vision pro at 35ppd simply isn't close to the PPD you can get from a good desktop monitor (we can calculate PPD for desktop monitors too, using size and viewing distance).
Apple's "retina" HiDPI monitors typically have PPD well beyond 35 at ordinary viewing distances, even a 1080p 24 inch monitor on your desk can exceed this.
For me personally, 35ppd feels about the minimum I would accept for emulating a monitor for text work in a VR headset, but it's still not good enough for me to even begin thinking about using it to replace any of my monitors.
