One advantage I see in using a technology device instead of a paper notebook is the opportunity comes from added capabilities of technology. When it comes to taking notes, I would propose that the simultaneous recording of audio linked to personal notes is a great advantage over taking notes on paper. The addition of the linked audio allows the note taker to revisit the audio in a precise way when notes are confusing or incomplete. A more complete and personalized representation of key information can then be generated after the presentation.
There are several different applications for doing this. The demonstration that follows makes use of Notability on a tablet.
