Yeah, and that's fine. What I'm saying is that when the computer is a primary mode of delivering course material or is otherwise absolutely necessary for the curriculum, malfunctions, whether caused by user error or otherwise, are unacceptable. Most schools just don't have the resources to support "real" computers in the hands of the students.
Yes they do. Most of them are contracted out to companies which have state restoration software on, so if someone screws it up, they can re-image it instantly.
