Consuming content is great of course but the AVP has changed my content creation: I take way more panoramas and now spatial photos (Spatialify on iOS works well). I also bought an Insta X4 360 camera which, while a far cry from Apple's immersive content in resolution, can still be a really nice way to relive memories.
More content: Last year I started 3d scanning (using Scaniverse) sculptures and other art / items that catch my eye during my travels. The AVP makes it really easy to import and place them in my environment. When I'm working I'll often place a favorite sculpture next to me for company & as a reminder of a trip I took.
Finally, even after 4 months of use, it's still really fun and, from a tech perspective, astounding in terms of image quality, stability, 3D placement, integration in environment, etc. I love it and I can't wait for this tech to get better and better.
