> I've read Altucher's words on using a waiter's pad and he says the same thing -- it's for ephemera. I've seen the way many people use physical notes and it's largely the same thing.

My thoughts exactly. When I think of notes, grocery lists and todo lists come to mind. In my opinion, the function of note taking is comparable to RAM. It's short-term and ephemeral. Notes may contribute to a long-term document that should absolutely be digitized, but storing the notes themselves defeats their purpose in my view.
