I have a q3 and it’s pretty solid for a couple hours. I do use a neck fan as I’m a sweaty person. Graphics are good though, and the quest doesn’t abstract away the filesystem - I can plugin a flash drive with content or literally scp movie files over to the filesystem on the headset. Just took an international flight and it was great with their airplane mode.

Am not a fan how Apple doesn’t let you treat devices as actual computers. Quest is android and didn’t lock us out of that.
