People really need to understand that its the details that make a product viable, not the concept.
The problem was the same as today. Dead numb market response to non-SteamVR VR/MR/AR/XR headsets.
HoloLens 2: 2048 x 1080 (per eye)
Vision Pro: 3660 x 3200 (per eye)
Yah no one was gonna buy HoloLens as a desktop monitor replacement. It really was a crap product.
People ARE using Vision Pro as a desktop monitor replacement.
So do people with other headsets. AVP's uniqueness is that it's apparently useless for anything else whatsoever.
This is from someone who has spent hundreds of hours coding in VR, which currently requires big font sizes and screens that take up massive FOV, which I find very uncomfortable for extended periods.
The masses don't consume everything on their phones because they care about screen size or fidelity. Sure, they will buy phones with bigger and better screens than other phones, but if they want to do something on a big screen they will use their 60 inch 4k TV
In fact, the masses basically don't do computer stuff at all anymore.
