The main thing I don't like about audio is not being able to highlight or reflect on things, even re-reading portions several times to really learn something.

The main thing I don't like about audio is not being able to highlight or reflect on things, even re-reading portions several times to really learn something. I like being able to cross reference materials and go deeper on things I read, and when I re-read a book, I see notes that I had forgotten about, which is near impossible with audio. It seems its all about high amounts of shallow exposure to different concepts, good for "knowing what you don't know" but not really learning what you don't know.
