While that's great, your scribbling on paper while coding can't sustain the enormous empires that were built up around the sale of paper. Things like books and corporate purchases are what did that. And if even just 90% of paper usage is eliminated in those contexts, you'll see those empires come crashing down.
What would happen to the price of paper if suddenly demand is decimated like that? If the price of light paper goods increases dramatically, I predict that consumers will increasingly adopt new note-taking/scribbling solutions (like and iPad app). After one new generation of people grows up accustomed to accomplishing all of their formerly paper-based tasks digitally (even simple tasks like doodling), I believe that paper will truly be a fixture of the past.
