Probably schools, those bad boys are pretty much designed to be used in schools. They are easy for the sysadmin to manage and they are easy to use for the student. They charge fast and stay charged for a long time, and most things a student would need can be found online. They also make it harder for a student to brick their own computer or do things they shouldn’t. Even if they are horribly Google-ridden, they do work well in schools.
