Why should my education and social life be negatively impacted because individuals decide to indulge in self-destructive behaviours? I use my laptop because it's significantly more effective for my education than pen and paper.
To answer your point, the group of people who are affected by this are people who use their laptops for notes. This isn't "a fairly small group of people". I'm just affected more than most: it eliminates my ability to take notes, rather than reducing the efficacy.
