I took all my notes in org-mode on a little Eee PC for my last two years and graduated summa. A representative quote from the article says, "research shows students who use laptops perform more poorly in classes." This is the standard statistician's fallacy of confusing individuals with Gaussian distributions. You are not a statistical amalgam; you are an individual. If you are too stupid to use a laptop as a tool without turning it into a distracting toy, then don't use one; but don't imply that everybody shares your malady.
