Sure, but name one technology that ALWAYS helps (Score 1)

Sorry to say, but that is profound bullshit up in the parent comment. You claim that maybe one person will use a laptop to distract people and thus it is OK to ban laptops? I claim that maybe one person will use a pen to poke someone in the eye and make them go blind, and thus we need to ban pens. Infact, some students even use furniture and logs to hurt other people. Let's ban furniture in classrooms now. See the trend? The slope is slippery, and once you start weilding your power to ban stuff, where is it going to end? I do see your point in that laptops aren't the universal solution for everyone, but if you claim that no-laptops is a good solution for "everyone" (i.e. a classroom filled with a diverse bunch of students), then I call bullshit.
