Yes, actively use it, average once a week currently due to space issues and being ill recently, will start playing more again in the next month.
Generally yes, and in my environment I have noticed more people getting a headset. It's more that people use it less overall, but more use it, and then do one co-op experience. Lack of good new titles is a serious issue though, though have seen a lot playing Ghosts of Tabor (basically VR Tarkov).
Completely fine for me, low fps/frame drops as an issue has also gotten less of an issue due to frame interpolation (basically guessing frames to double the frame rate, e.g. 45 -> 90) if low frame rate if playing on a headset like the Quest.
People who are nauseous within a minute of putting on the headset, wouldn't have them play, anyone after 10-15 minutes can get used to it, just a case of playing in moderation, and the right types of games (first 1:1, no movement around, and your movement matches game movement, then something like beat saber or pistol whip, where you stand still and world comes to you, and then after that ones where you move using left controller).
Content is still an issue, but tbh, there is "enough" now that there's always something to play, games like Contractors/Pavlov/VR Chat have a ton of community content to explore. VR Chat I am mostly using for escape sims, Pavlov/Contractors for Halo, and Nazi Zombies.
Right now my titles I am going through are:
Staple:
Pistol Whip, Eleven Table Tennis, Contractors (mods, built into the game).
Playing through:
Red matter, bonelab (mostly mods).
Not really bailing, it was just them failing on meta verse, hasn't really impacted anything.
That's going to be dev stuff (rumored price is $3k), only thing that will do is hopefully bring more interest in the platform, not going to affect normal consumer for a few years.
Moose uses an index I think, so he doesn't know the improvements on Quest.
Quest's been getting a lot of improvements, still now. Things like:
(March 2022) ASW (frame interpolation headset side):
https://mixed-news.com/en/meta-quest-2-next-update-brings-new-pc-vr-feature/ (synchronous / SSW on virutal desktop) though that's a bit ago.
Recording can now be set to 1080p / both lenses, can also have headset apps update via phone if on, and also set to auto update when I shutdown. Also have media sync so recording on headset syncs to phone; can also have phone notifications pop up on headset (this is a hit or miss for me with telegram, works fine for other apps, basically like pushing notifications to my watch is its reliability). Hand tracking has noticeably improved, guardian system on beta I can bring in things like table/couch, so nice for break while keeping headset on and still chatting with friend. Will be interesting to see what else they bring, think next larger stuff will be new hardware instead (quest 3 expected end of year, focus will be on pass through).
Meta is dropping Quest 1 support, so they'll hopefully finally have apps with better quality on the headset direct now. Was understandable to force backwards compatibility for a while, but they should have set an end date earlier while still keeping quest 1 support (quest 1 will still work wired / apps that are on it, including wireless streaming, just party grouping/social features don't; support drop has a large chance of being due to the SD835 in it, from 2017, QC is notoriously bad for support).
If on an Index / direct on PC, your improvements are mostly if PC improves. There have been changes like allowing you to not launch Steam Home, which supposedly can actually be quite an improvement on lower end hardware. Otherwise not much has/will change there, just how much devs optimize their game, and what settings you set it at.
