I was thinking of a A6 paper agenda: I've used the Palm for 6 years, I love it, but capturing things on the spot is most quick with paper. I'll use the Palm to put the lists, as DA suggests. How does it sound? Also, the PocketMod is very very handy. I've been using it (in non-GTD terms), and I'm very satisfied. I'm using a pencil, instead of a pen, so I can delete the "Done" items.
