My understanding is that students are very hard on school provided laptops, I don’t think many of them that have been in use for a year will be in good resale condition.
And even after that, yes, children are absolutely hard on their tablets I agree but they operate and the resale value of those could be decent aside from a very few IMO. There is a way to create a culture of preservation or atleast steer things that way but yeah I agree it can be hard.
