My high school did the one laptop loan out thing (later got sued for it) and I can tell you it was useless as a learning tool. At least in the way intended. I learned quite a bit mainly about navigating around the blocks and rules they put in place. In high school my friends and I ran our own image board, learned about reverse proxying via meebo repeater, hosted our own domains to dodge filtering, and much much more. As far as what I used them for in class... if I needed to take notes I was there with note book and pen. If I didn't I used the laptop to do homework for other classes while in class. I had a reputation among my teachers for handing in assignments the day they were assigned.
In college I slid into the pattern they saw here. I started spending more time on social media, paying less attention in class, slacking on my assignments. As my burnout increased the actual class times became less a thing I learned from and more just something I was required to sit in. One of my college classes literally just required me to show up. It was a was one of the few electives in the college for a large university. The students were frustrated they had to be there, and the teacher was tired of teaching to students who just didn't care.
Overall I left college burnt out and pissed at the whole experience. I went in wanting to learn it just didn't work out.
