Woah... thank you for sharing RE the Pencil, because that was the only killer feature that I could think of that would get me to buy the Duo. Taking notes during an in-person meeting with the pencil feels (and looks) much more "they care about what I'm saying" VS "they're texting/emailing someone" (when typing on a phone or computer).
And even with mobile dictation/notetakers, there's something that screams respect when someone writes actual notes down by hand.
Big big deal indeed, thanks for sharing.
