Oh, that'd make sense. I think the quest 3 has a depth sensor, but they mostly use that for room setup. I don't even think it has IR emitters for low light. But that's the age old question about patents, if they're being granted too much they stifle innovation and competition instead of the opposite... (which is the point you were making as well).

On the quest 3, I've felt like the screen is just a bit too low res to use comfortably as a monitor anyways, so I imagine the Frame won't be much different. The better weight distribution should help a lot though.
