Apparently the glare on the pancake lenses is coming from light leaking in from the sides of the padding. Better fit/ padding eliminates the glare, and the glare is already far less than the Fresnel lenses on the Quest. No Godrays, double vision like astigmatism etc.
So far the padding is the biggest gripe I've seen with the Pico 4. It doesn't seem to fit everyone's face, and is kinda hard for some people. Mind you, most of these reviewers aren't using the stock oculus/meta padding and have upgraded their units to 3rd party manufacturers and are probably used to the fancy upgraded padding.
The bottom line in A LOT of reviews is, if you already have a Quest 2, no need to get Pico 4. If you don't have a Quest 2 or are just entering into the VR landscape, Pico 4 is a great investment.
For Porn-centric review. Have to wait for the DeoVR app to launch. The dev team has either just got their unit now, or are still waiting for one. DeoVR started working on the app for Pico 3 in Jan and it officially released July (from what I can glean from the deovr forum https://forum.deovr.com/?q=pico) That was their first foray with Pico, so it shouldn't take long to set up the new unit.
This is where I'm on the fence. I have an old Oculus GO. It's fine for movies, but I rarely use it. I had the Oculus Quest and found the screendoor was much more apparent on the $600 unit than the $200 GO. So I sold the Quest. Weaned off FB/Meta, don't really care for jumping back in to their ecosystem.
All those things considered, Pico 4 seems like a great option. (yes, I know they're owned by tiktok's parents and that's a bit scary, but, so far you can sign up with any email address and don't need a social media account)
Pico 4 has a lot of potential, and the OS seems to be getting a lot of updates (initial reviews had glitches, but that seems to have been fixed.) Still in the cart, haven't pulled the trigger yet.
