I've been using my AVP pretty regularly since release day. I'm using it less now that the novelty is wearing off, but still fairly often.

Things I like:

1) It really is an upgrade vs. working on just my 16" MBP screen. I'm in the minority that actually finds the knit headband pretty comfortable, and can fairly easily go 3-4 hours with it on before it starts to bother me. I do wish there was the option to break specific OSX apps out into their own window or at least have multiple screens, but when I can put most of my work in a web browser or app that the AVP supports, it works extremely well. At worst, it's still more eyeball real estate than just the MBP screen itself.

2) ALVR/Moonlight actually work pretty well, if you have the WiFi infrastructure to support it. It works properly on my Unifi setup but it struggled a bit on a friend's wifi. But it's really cool to play PCVR games using such a high resolution display, as well as playing 2D games on a screen that appears far larger than even my 65" TV

3) 3D movies are insanely good on it. I've always wanted to really love 3D movies, but the downsides for both active and passive 3D really kept them from being a resounding hit with me. Not the case on the AVP. No compromise on brightness or FPS makes it a much nicer experience. 2D movies and TV are also quite nice, with the only real downside being the audio - it's reasonably good, and I can enjoy movies on it no problem, but it also doesn't match proper home theater audio. On the whole, though, I think it's the best personal movie watching experience you can get for 3.5k. A projector that even approaches the visual quality/relative screen size of the AVP is $5k+. Obviously, though, a real home theater setup can be enjoyed with more people. The individual nature can also be a strength, though - if you want to watch something without disturbing your partner, you don't have to have a TV on in the bedroom.

4) I feel significantly less disconnected from the world when using it than I have my other VR/AR headsets. I can function with it on moving around my house, etc.

Things I dislike:

1) I would love it if it was lighter and I could wear it all day, but it's not a huge deal for me.

2) The OS is miles ahead of my Quest Pro, but it still feels unpolished at times. When everything works it's perfect - but there are still some bugs. Until 1.1 released, something was going on with Safari that could bring the whole thing to it's knees until you rebooted it. Not sure if it was a memory leak or if it was something else, but if I had a web browser open for an extended period of time, it would eventually bring the whole system to it's knees. This is fixed, but I still have some (more rare) issues with apps going nonresponsive and not being closable via the usual X, etc., requiring a force quit. I'm sure this will all get fixed in time, but it's not the same level of polish I've grown accustomed to with Apple software.

3) I'd really like some way to sync audio to external sources. You can do some hackery with a Siri shortcut, but I'd love to be able to sit down on my couch, put on a movie, and watch it while making use of my sound system vs. being forced to go with the AVP speakers or bluetooth headphones.

All in all, I like it quite a bit. I don't know that I would recommend it, with the pricing being what it is - I think if you're a good fit for it, you already are interested in it or will be interested in it when you hear about it in general.
