What I've heard from a school library: they have iPads and Chromebooks, and the kids all want the Chromebooks because keyboard. Now consider that the iPads cost twice as much.
I had thought that the convenient form factor of lighter, less frills tablets would make them continually more appealing to kids or less technical adults regardless of where the device is used. But that does not seem to be the preferred case in a school setting, especially as a student gets older. I think it reflects a desire to be taken more seriously, and the appearance of the tools being used matters a lot, even if the same type or quality of work could be done using a Chromebook or iPad.
