I love how any education-related topic brings out the armchair-pedagogist out from the woodworks. Of course a big aspect there is that everyone has encountered some amount of education, and especially both courses they enjoyed and disliked. And there is of course the "think of the children" aspect.
To avoid making purely meta comment, in my opinion the ship has already sailed; we are going to have computers in classrooms for better or worse. So the big question is how can we make the best use of that situation.
I noticed that the article is speaking from a university perspective. I work in the high school realm, where teachers have more ability to reprimand students not on task. That seems to help students use computers more effectively, but at the same time it requires some effort on the part of the instructor.
