Smart Pen, that allows you to digitally record all your notes from classes and lectures via smart software which digitalizes your written text, and a sensitive microphone which records audio.
I saw your list of resources for school and I just wanted to add that there is a thing called a smart pen that some universities have. Its a pen that can simultaneously record lectures and take notes. You can easily upload the notes to your computer (through a usb drive on the pen) to have them digitally along with the audio file (and if your professor gives you the powerpoint you can sync it all up). My on campus ODS is giving me one in the spring so I haven't tried it yet, but it seems useful
