If you can afford a $3,500 product you won't be flying economy like that lady. I could see some of us on a long late flight maybe using it to drown out those around you. I see passengers with AirPods Pro Max and the Vision Pro is not too far off especially for a mostly stationary device. Also, I was able to charge my iPad and iPhone on a return trip, so using it for long flights won't be a problem. Apple might solve the content issue and wifi by letting you stream content from your iPhone or iPad (many Vision Pro users will have either one already) or the Vision Pro might come with 128 GBs of storage to store offline content.
A lot of this is still in the planning.
