I keep a smallish (3x5"?) leather-bound mead journal (the ones with graph paper) in my cargo pants and a Pilot G-2 gel pencil in my left pocket. Everything goes in said journal. Ideas, information, sketches, IP information of the schools I work in... It's batteries never run down. It's memory never becomes corrupt. I don't have to transfer the information when I perform a system upgrade. I have access to it while in remote locations (hunting/fishing/hiking-- I have a lot of ideas in the middle of nowhere.) It has a .5 second boot time and auto-loads notepad. I'm very rarely without my cargo pants/shorts.
