Hi Ray,
It was a quite comprehensive discussion on the pros and cons of using digital technologies at classrooms. As a computer science graduate student, I have always carry my laptop to any classes. It is often essential to be able to follow-up what the instructor teaches on my laptop. On the other hand, I can understand those people who dislike the idea of having laptops in classrooms; as depending on the topic, laptops might not be a helpful learning tool but just a distracting device besides cellphones and tablet! Therefore, as you mentioned, I agree that “the use of technology in the classroom is self-evidently situational”.
