actually what about immersive 3d experince design ? imagine being a game developer and having this in debth experince with your game visuals.

same goes to vx effects in movies.

what about designing App UI / UX where you're completely in the flow and don't want to be disturbed.

how about complex data anylsis ?

If the price was not an issue and apps are mature, I could defenitly imagine lots of use cases around immersive work tasks ...
