iPads in schools definitely contribute a lot to total sales revenue, but I don't think they're the majority users by any stretch of the imagination. Plenty of school districts also bought into the GSuite + Chromebook fantasy so they can't be the only reason iPad is doing so well.
Anecdotally, I've seen that GSuite + Chromebook has worked wonders for my high-schooler sisters. Assignment hand-ins can be done all online, no problems with file compatibility, and homework can be accessed anywhere with an internet connection.
Sorry, I probably used the wrong word there. I was referring to the fantasy tech companies try to sell school districts that buying X technology will radically alter education forever; as long as you spend your money with them.
I used Chromebooks in high school and they were quite nice, but they didn't completely evolve my relationship with education. They were tools and not much more than that. Certainly not part of an education revolution. Definitely useful for writing papers though. I imagine districts that bought iPads are content with them as well.
