I'm using it ocassionally - whenever I have time to do further WebXR development beyond what I've already done, and when an interesting new immersive video or 3D movie becomes available on it. I'll sometimes use it to relax and catch up on any new VR180 videos on youtube.

For other work or entertainment that doesn't take advantage of its spatial features, I tend to revert to using a computer with an external display. The display in the Vision Pro cannot quite match the resolution and HDR headroom of the external display I ended up having (a Pro Display XDR). Maybe if it didn't get outclassed by my external display when displaying 2D content, I'd have additional motivation to use it more often.
