Apple continually misunderstanding that you need a keyboard if you're going to go against Chromebooks in education.
Plus, it's easier to add a keyboard to an iPad than to remove it from the Chromebook (and replace with touchscreen).
I hear the Chromebooks are easier to deploy/manage, but like the iPads, each kid gets one.
That said the kids prefer the iPads. I'm not sure if/how the Pencil will change the game.
