Turns out that this was, as you probably suspected, a staged destruction of the laptop, designed to convince students to not bring their laptops to class. The point regarding classroom management still stands: Refusing to allow students to bring laptops to class (especially in a physics class) is kind of silly.

There is a response to this video where a student says that laptops are annoying, stating, "The professor doesn't want to have to walk around the classroom, checking to make sure everyone is on task." The fact of the matter is that students will get off task, regardless of the inclusion of technology in a lesson.
