On the other hand , and in the real world, a majority (citation needed? I can give you anecdotal evidence from each of my 18 years of classroom education) of the students would be distracted by laptops. Forget laptops, I bite my hand regularly in classes just to keep awake and concentrate on what the soporific prof was talking about. Even a scribbling sound would distract me in his lectures, and I would end up dreaming from scratching to itching to that advert about itches to that model in the ad to that film about a struggling actor to latest movie to upcoming movies to next week plans to booze and sports. In an economics class. This actually happened.
I felt it was the professors reponsibility to stop me from dreaming by atleast pretending to not mumble. But I would be pissed if some other tech, which enables me to take notes, is banned.
All said and done, I wouldn't be too sad to see laptops banned.
