The Livescribe digital pen and paper system, which we discussed a bit before, has shown what is probably the production model of their pen. It's hefty, but still pocketable. If they make a nice little Moleskine-like notebook with their special paper, I might even give it a shot.
Livescribe is taking pre-orders for the system now, although it won't be ready until early next year.
