The thing is: When working with the material afterwards the important part are the small details. The talk/recording are good for the high level overview and following along on the big picture, but for details it is annoying as one has to jump around for specific words and phrases. Something written or an image/diagram is a lot better to study in depth.
And there lies the trouble with slides: During a talk they should support what is being said, but they are often abused as also being the handout for afterwards.
