I think this is kind of a thing for a lot of stereoscopic 3d technology.

I could play the virtual boy, 3ds, watch 3d movies, etc. for hours without issue, and other people can’t take it at all.

I don’t know what factors play into that, maybe it’s genetic, maybe there’s some kind of skill/technique/habits about how you focus your eyes, or how often you blink, maybe it’s just luck of the draw that your pupil distance is just right or wrong. Maybe it comes down to something ridiculous like how many hours you spent trying to make sense of Magic Eye books when you were a kid.

I have a theory that the intended to do it in 2020-/2021, but COVID chip shortages and such threw a wrench into their plans, they already had their hands on the OLED panels they planned to use for them, but couldn’t get whatever they needed for the rest of the upgrade, so they came out with the OLED to use them up because they decided by the time things normalized and they could ramp up production on the refresh it would’ve been to late in the switch lifecycle to be worth it since they were already kind of pushing it to begin with.
