I have a cousin with a learning disorder called dysgraphia–he produces handwriting with all the ease and elegance of a somersaulting dumpster, and needs to be accommodated with a a laptop in school in order to keep up. For him, forming letters is a miserable barrier between his thoughts and his production. However, for most people, I believe there’s a consensus that there’s a mild advantage in handwriting things for learning–and mind-mapping software requires quite a learning curve to even approach the ease of pen and paper.
