I have long lived innparallel universes. I am, of course, a geek who lives in a digital world. Long striving for the "paperless" life, yet never achieving that elusive goal. As a "recovering" architect, I am not sure I really want to completely abandon the world of paper and pencil. For me, sketching and taking notes with paper and pencil is still a very visceral experience. That tactile experience of documenting your thoughts via words and sketches, on paper, with different writing instruments, each with their own unique "feel" is one that still does not translate well to keyboard and glass.
All my digital devices still seem to push me toward very organized and linear processes. Which is a good thing most of the time. But often, when I really need to "think", to do some serious creative problem solving, to get at the heart of an idea, I will put away the computer and the iPad and grab paper and pencil. We used to joke in college that the final exam at the University of Texas School of Architecture was to explain and idea or concept without paper or pencil. If you were able to do that, they would hold you back for another year ;-)
With all that said, take a look at the video below and see if you don't find it as intriguing as I do.

And if you want to try a smart notebook, you can order one from Moleskine or just do a search at Amazon and have it delivered to your door in a few days.
