For the uninitiated 3DoF means the headset only tracks the rotation of your head, not your heads absolute position as you move around, while 6DoF tracking does both. 6DoF is also much harder to implement.
Besides, VR is already cheap. A new Quest 3S is just $300 and can do pretty much all of what the $3500 Vision Pro can do (just worse); if you just want VR games you can get used 6DOF-capable PCVR or PSVR headsets on eBay for closer to $100.
6DOF, even when sitting, is a significant difference. Your brain immediately feels far more at home with good 6DOF.
Fun fact : one week I spent about 5-6 hours every evening playing Elite Dangerous in VR. Mining asteroids while listening to lofi cyberpunk and pretending that mining was my whole life, it was great. Until my partner would bop me on the back of the head ^_^
Besides 'it's Meta' ; what is it doing with my privacy? I mean actually proven things, not 'probably it is'.
(I am not saying it isn't, but I haven't heard anything in this regard, so it would be interesting to know)
this line of argument don't help the discussion.
both companies report millions from selling your information, so assume they are always amassing loads of it, to sell when the price is convenient for them.
I'd like to place a picture with a QR code in it, have somebody scan the code, then have the option of jumping into a world.
Apps can't access the cameras so you can't write a QR scanner. The Quest has a decent web browser but you can't access the cameras and make a web based QR scanner.
Without access to the cameras apps cannot at all understand the environment and enable you to interact with it. AR apps now have a special module that identifies a physical volume inside your space on a session by session but that's a pale shadow of the SLAM tracking of the Microsoft Hololens and Apple Vision that let you stick a "hologram" into the corner of your office and have it stay there.
Quest 3 devs need more access to make more interesting apps.
I want super high res so the quality is comparable to a TV or projector setup, and I want OLED because of contrast performance for dark scenes.
I've had pretty good experience with https://goovis.net/products/g3max specifically for movie watching. It has 2560x1440 (per eye) OLED, so not quite 4K; I do hope to see a proper 4K headset like that some day for a reasonable price.

For $200 they are good. They are native 1080p Sony micro-OLED panels. Brightness and contrast are excellent. I got them mainly to use when traveling, but I also use them laying in bed sometimes.
The resolution is higher than it seems because the 1080p is only displayed across about a 40 degree horizontal FOV, so the PPD is actually very high at about 49, which is markedly higher than even something like the Apple Vision Pro. It's also RGB stripe OLED. I cannot see the pixels like I can with VR headsets.
But alas, there are issues that bother me like ghosting and other internal reflections inside the lenses. Though all VR headsets I have tried have these issues which bother me, so I am not sure if that will ever actually be solved to a level that is unnoticeable by me.
The other thing about the glasses is that they don't recreate a theater, and a virtual room, so the apparent size of the virtual screen isn't consistent as it mainly depends on your imagination for how big you imagine it being. If you view a virtual screen in a fully virtual environment like Bigscreen Beta, then you can fully trick your brain into making the virtual screen seem as big as you want, even IMAX sized, and it really does feel like it.
The problem with full VR environment headsets and large FOV over 100 degrees means that the virtual screen only takes up at most about half of the panel, because a 55 FOV for a virtual screen on a headset with a 110 FOV is about as big as most people would be comfortable. So then a true 4K per eye headset would still only give you a 1080p victual screen. Though I think this is still a level which is good enough.
Once the technology started emerging, I was so exited about the potential. A few games gained support for shutter glasses etc, but 6dof was hyped up so much that everyone jumped on that train instead.
I think of this kinda like the data collection with many phone apps. I understand that it needs access to the networks to make connection to wifi or bluetooth, but why is this bundled together with an app's ability to record and send that data back to the developer? There has to be a better way to handle all this.
