If I may, people write (with pens) slower than than can speak, and thus to take good notes you need to synthesize the material you are being explained. You need to understand what you're writing.

Many people can type as fast/faster than they talk, and when typing it is possible to try and type verbatim what is being said. In this case, there is no understanding. (If you've ever taken a class not all that is said is pertinent and not all that is pertinent is said)

I personally don't revisit my written notes their purpose is uniquely for me to remember/understand what I've written.
