Damn... I just planned to buy a new quest...
I mean, the device is still being sold and it's not like you are missing out on anything, unless you are one of the 3 people on the planet who actually uses the "Metaverse". Most people use it for games, and it's fine.
I have a Quest 3 and I think I've only opened Horizon Worlds once. It's a very small part of the overall offering. If you can find a used headset for $200, it's a no brainer buy
