I am able to take notes in class using email. I have a WordPress site for my course and have set it up so that I can post via email. All I have to do is to send the email to the special address and I have a posting with my notes.
I find that this is as quick as me writing, and I can later add images, extra notations, or link to videos or audio for richer notes.
I can create an outline and make each heading a link to a note posting.
