University professor since 1999 here. Different schools have different processes for handling e-textbooks these days; not everyone does it with tuition (we don't). I've never seen an explicit requirement that students must have a laptop but they all do. There are indeed a few students who take notes on paper but yes, the vast majority now do on laptops or tablets. Paper is indeed now a rarity and yes, pretty much all assignments are now given out and handed in electronically.
What I don't understand is your objection to this. I promise you that there are ZERO students clamoring to going back to the old system. Just because you prefer paper doesn't mean that the current crop of 18-22 year olds do.
It took quite a few years for academia to figure it out. Now, etextbooks and faculty generated notes, etc., are fully searchable, accept editable markups and have links to all references. Nobody where I teach, students or faculty, wants to go back to hard copy books, notes, or assignments.
