I've thought about it with my Quest 2, but decided against it because of the bulk of the headset and controllers when it comes to just carrying it around, the clumsiness of using the controllers in an airline seat (even a nice one), the difficulty of easily switching in/out if someone needs my attention, and how it's a pain in the ass to get media files on to the device. The Vision Pro has seemingly solved those issues so handily that I absolutely would have brought it if I had one in the same circumstances.
Yep. I don't know if I'd do it with an Apple Vision either but I do know almost for sure that I wouldn't with a Quest 3 because of the controllers. Whether there's other reasons that will prevent me from doing it is unknown to me.
