I bought what was affordable on the used market. And VR stuff is almost entirely Windows exclusive, with only the Index having a native Linux compatibility via the recent SteamVR Linux port. While the Quest series (and a Pico, its Chinese competitor) run a special version of Android, they don’t have the performance in standalone mode that a PC has. Besides, my library of VR games are all on the PC.

And before you say “you shold have Index”, I will point out the very, very high cost and requirement for external tracking hardware, aka “the lighthouse”, something I lack the space for.
