I tried the HoloLens ages ago and honestly the only upgrade would be the display & how often the inputs worked. Microsoft was demoing the HoloLens @ some hackathon and had a program where you could flip pages in a virtual book. On top of the book looking super low quality / illegible, I could never get the controls to work. The only thing that will make the vision pro seem like a worthwhile purchase would be if the controls worked flawlessly. I already have faith in the displays & picture.
