I recently bought a MBP and made the decision to loose the papers and go fully digital in the classroom. Notetaking has never been more efficient and fun, but there are a few issues I have to ask about... Often while taking notes in class, I find the need to draw certain things like graphs and diagrams. This is very cumbersome even with a bluetooth mouse, let alone with just a trackpad and your finger. I need a "stylus-like" pen device that I can hookup to the MBP that works with its trackpad to navigate the cursor. I don't need a 100-200 stylus+tablet. I only need a small pen like gadget. Do they even make this thing?
