meta etc didn't move to inside out because it was cheape, they did it because they were more user experience driven and knew that is how it has to be done in the future. I haven't rad about apples or if they have said what they are doing but I can bet, being a user experience driven company it will have inside out tracking and lighthouses are not what users want.
The biggest reason for inside out tracking in a stand alone headset is that you can just turn it on ANYWHERE and use it. That's another reason they are pushing direct hand tracking. If they can make it so you just carry one thing and simply put it on and then drive it using your hands they have made it even more accessible.
For a PC VR enthusiast system lighthouse tracking is definitely the way to go.
1. You have perfect tracking that can't be thrown off by motion.
2. There are no issues with large flat surfaces.
3. The lighting can be anything you want. Play in the dark if you like.
4. The calibration takes about 10 seconds and is perfect from that point on. No matter how tall a person is, they just put the headset on and everything is normal to them.
And if you look at the cost of these enthusiast headsets, the base station cost is pretty well moot, so why not? It's a set them and forget them situation that works reliably for years without any adjustment, recalibration, clearing of setting, nada, nothing.
You do make an accurate point about expensive niche headsets pretty well needing to go in this direction. The MaganeX headset is a perfect example, they tried inside/out and failed, so they defaulted to SteamVR. Inside/Out tracking is hard. HTC's first attempt bombed. Oculus/Meta is the 800lb gorilla in the room and they have something pretty good that no one else has matched and it still isn't as good as base stations, but it has other strengths making it perfect for stand along headsets. MS tried to do the same thing as Valve with WMR. They licensed Inside/Out tech so companies could jump in easily. Unfortunately it wasn't good enough to be viable for many people.
So here we are.
If I could put my sim rig in my pocket and carry it with me, then I'd care about inside/out tracking, but given my rig never leaves the room with my gaming computer, it seems pretty pointless.
If I wanted a stand alone headset I would get a Meta product, period.
Getting back to Pimax and Valve. Part of me wonders if Pimax saw the early leaks for the next Valve headset and made some bad decisions based on that. Swappable lenses, wireless operation, and stand alone capabilities seems like a serious divergence from their core users and a lot of added complexity to figure out and get right. They DRAMATICALLY increased their potential failure points. Their average users are not room scale players. Their headsets are way too bulky to whip around quickly. Their users sit in flight or sim rigs. I can almost guarantee that they will have a LOT of teething issues with that headset. It will come late and buggy.
