Despite my love of computers and digital devices, I still think there's something special about a good notebook.  For years I tracked daily accomplishments and goals in date books, until I switched to a PDA.  Something was missing, though.  It's fine for appointments and tasks -- after all, a notebook won't beep at you -- but the things that were really useful to me: recording data, events, and work done... that just didn't fit well in a digital setting.
