As a college student, I carry around up to 10 different notebooks at a time for various classes and labs, but the Pencil support would allow me to finally digitize all of my notes, and consolidate all of those notebooks down to a single device that weighs as much as my laptop. While the Surface, and other devices, support pen input, as well, nothing in my testing has been able to replicate the same feeling of pen/pencil on paper, as well as the iPad Pro did in my brief encounter with it. From everything I read on the subject, this is incredibly exciting to me; to be able to reduce my backpack weight tenfold by replacing my notebooks with a single iPad.
