Earlier quoted context omitted.
Chromebooks are the best, my school has them, and they're 100% usable in all non-tech classes. Battery lasts forever, great for typing, and everything is a web app anyway. We had iPads at one point, but luckily the school realised those were bad and I haven't seen them this year at all.
I also see comments about programming on them, that'd be painful. For everything else (that matters at school) though it's 10/10.
To help smooth the process of having them program on their own, I send home a writeup with how to install everything on a home computer for different operating systems, how to ask questions on StackOverflow and give an email address I have manned by other students that like responsibility.
I've worked off of them a few times, they're basically useless without internet is the only major drawback - if you connect to a RDP session the battery will last forever.
