Pen and paper is definitely the easiest way to record an idea, but for me when it comes to expanding that idea into a piece of writing, the ability to edit does help me say what I want to say in the way I want to say it.
Perhaps it is partly down to how you did things when you were younger, I was typing my school work on a Psion Series 3a when I was 15. I suspect the young'uns today would also mostly prefer digital.
The simplicity and ease of use in pen and paper means that it will always be in the game though. Good piece.
