I've noticed that a lot of people seem to think there is something fundamentally wrong with it. Some have told me to stop doing it despite having never seen my desk. Whenever I mention it to people (which I seldom do nowadays) I'm told to just write on paper like everybody else. Thus far nobody has been able to explain me what I stand to gain from the switch. Few people seem to accept my justification (I find dealing with pieces of paper inconvinient) for my behavior either.
