Hey, I've found a way to easily take notes in my classes with my playbook. Here's a video of my method.
Paperless Note Taking with Playbook (prototype 3)
You can make one of these yourself with minimal money and effort. I've been using this method for two semesters now as a Mechanical Engineering student. It's worked wonderfully so far, and it's really nice to have all my notes in my playbook everywhere I go. Another thread with this idea can be found here
