But you can plug the Quest into a PC and use it as a PCVR headset. Oculus sells a 16 ft fiber optic cable for $80, but it works well over any good quality USB 3 cable (and even works over USB 2 now).
The downside of this is that it's more front heavy than a PC headset without all the standalone guts, and I'm sure there's non-zero latency for running the video stream over a USB connection rather than a standard video cable. It works pretty well though, I think the trade-offs are absolutely worth the benefits of having a standalone headset.
