I think I heartily agree; writing sermons (which end up digitised) with pen and paper is, for me, a great help in the creative process. It usually involves isolated sentences on scrap paper, some more coherent paragraphs and quotes in a moleskine notebook and, sometimes, something approaching a mindmap (but more linear) on a piece of landscape A4. Last week, the A4 became A3 and that was a very interesting departure.
