All of them? Probably not. But probably enough that, at least in some schools, they can keep re-using them for 10 years. Elementary schoolers are pretty hard on them, but my daughter is in Middle School and she takes good care of her Chromebook. They must be either cheap to replace or don’t get replaced often, because the insurance for them, if you want to pay it, is only $20.
I think that this will likely help schools. Maybe not all schools, but some schools.
