Hmm. Still renting because I like to move every year to try out new places (don't own a lot of stuff anymore since digitizing my papers/books/photos/music/movies & going to an iPhone/Chromebook/Roku setup), so no house (yet).
1. Her car
2. My lemon my car
3. VR setup
So #3 would have to be my VR setup. Gaming PC + $800 Vive HMD + expensive VR games + misc. accessories (VR exercise bike, subwoofer backpack, etc.). Still adding to it because eventually I'd like to add a seated HOTAS/wheel setup for various racing/flying/space games. Virtual reality gear has been a huge budget sink this year, haha. Totally worth it though because I have a blast using it & it's segwayed into a useful cardio exercise setup.
Come to think of it, I don't own a lot of expensive stuff. Interesting. I have a projector, but that was less than the Vive. Still rocking my T2i dSLR from years ago. A bunch of various kitchen appliances. I think that's about it. If I got robbed, someone would have fun watching movies & cooking well, hahaha.
