I think it depends on the person. If I don't take notes I naturally end up daydreaming and have missed an important concept by the time I snap back to reality. Taking notes forces my mind to pay attention to what is being said.

I'd say it's mostly a bad advice, seeing how people abuse it, but if you can restrain yourself to just a few words here and there it's actually good.
