I personally don't like something that is on my head for a long period of time and I don't specifically see it being useful for most people. I think it would be great for specialized areas like training doctors as an example?
This has been my argument about it from the start - headset based computing carries a significant cost in terms of wearing a headset. That cost is worth paying, if you can use your architectural CAD software in the immersive 3D space - not looking at a 2d screen floating in the air, but standing in the model, and walking around inside it, so you can get eye-lines, and feel the gaps between doorways, tables etc.
A 3D workspace, where you do 3D work, that's the benefit you expect, for the cost of wearing a headset, because that's the thing you can't do on a flat display.
eg with rhino:
Or with a Voxel sculpting tool like Kodon (Z-Brush equivalent), where you can move the tools three dimensionally in three dimensional space:
I'm not convinced that the Apple-centric developer community is culturally inclined to the task of making these sort of tools, and more importantly, I'm not convinced that the sort of people who make these sort of tools are culturally inclined to make Apple-Only solutions, or deal with the sort of hassle that is Apple's App Stores.
So we get back to what does the Vision Pro do well, that makes use of stereoscopic projection as its fundamental utility - looking at an OmniPlan chart? Notes.app floating in space?
Head mounted displays real innovation, the fundamental killer app function of them, is the Z-Index, and Apple seem to be regarding that as a UI novelty. 🤷♂️
