I defy anyone to reproduce a chalkboard full of eqvations, diagrams, arrows, etc., with a laptop and keep up with the professor.
Besides, my spiral notebook's battery never gives out, it's light, it's $.79, nobody is going to steal it, it doesn't make any noise, it doesn't distract anyone behind me, it won't break when I drop it, etc. Besides, no notes are complete unless you have a coffee cup ring on it.
You raise some good points, and many of them are related to why I take most of my own notes on paper. However, laptops far excel spiral notebooks at their ability to produce coffee rings on your notes; with the latest algorithms, you can produce many such rings per second!

Disco is music's greatest achievement, too.
