I have seen tons of university students taking note on their iPad with a pencil. Felt like a legit usage: read the course material on the iPad instead of printing everything, annotate PDFs, take notes.
Back in my days we were printing the slides and annotating (sometimes) them. That was a big waste of paper.
Fascinating to call printing a few hundred pages a "waste of paper" but buying a $1000 device to act as paper is somehow not a waste.
Yeah, I used an iPad and an Apple Pencil all through college. Lifesaver, I did all my homework on it and skipped paper completely.
Being able to turn in something handwritten, with whatever diagrams and stuff I want to draw, but also with the ability to quickly erase, move, shrink, etc. handwritten text on the fly removes a ton of friction from the learning process for me.
