I'm a HS teacher. I was so happy when my school finally phased out iPads as the designated device for our year 7 students. It's such a rubbish device for content creation. The touchscreen is a POS for anything other than web browsing and casual games. Teaching coding, image manipulation, file manipulation was utterly painful or impossible.
Typing on them is beyond painful and of the hundreds of students I taught, fewer than a dozen actually bought a physical keyboard. This meant that every task took 3x longer than necessary.
On top of this they are expensive. To anyone even remotely IT savvy it was clear from the get-go that this was going to be a failed experiment. Unfortunately education, like most other things follows the fashion of the time and everyone had to learn the hard way that a traditional computer is superior in every conceivable way.
Chromebooks are rubbish too, so I don't really see the move to them as a positive either.
