Meta did sell over 20 million headsets. The Quest is definitely lower-margin hardware than Vision Pro, but in terms of install base that's an order of magnitude larger audience.

Apple really screwed themselves by only supporting WebXR for cross-platform VR experiences. Soon Valve will ship the Steam Frame, which will likely cost a fraction of the Vision Pro and support bog-standard PC games like H3VR, flight simulators and flatscreen PC titles. Meanwhile, AVP owners will have paid $3,500 for a more powerful chip/headset with a fraction of the content library and featureset that Valve and Meta offer. Vision Pro's lack of audience is entirely a self-imposed failure, it seems.
