As for screen vs. paper. I agree, I hate reading things on screen, and do so only to try to save paper (and because there are a great number of things you can only read on a computer screen.). But I think this is changing. A generation of people who grow up reading things more and more on screen, vs. on paper, don't mind it as much. In fact, I've known some people to say they prefer reading things on screens because they don't have to deal with flipping pages. Furthermore, as screen technology gets better, reading on screen will become a more pleasant experience.

All too often, there is a new edition required by the professor.

The college bookstores sometimes buy back books (for which they pay the students a pittance) and then turn around and charge much more than that as the used price which is still somewhat less than the cost of a new book.

The text book companies cry about all these reasons why their books cost more, (which are decisions they made in the first place, why do I need full color glossies in a piece of junk I'm only gonna look at for four months of my life?) but look at the numbers they make a ton of profit, which isn't much of a deal, every company has a right to make tons of money. But when I'm looking at my shrinking bank account, I just don't have any pity for them.
(one thing that has saved me $300 and counting is to wait for the first day to get my books. Most of the time teachers will say, "We won't be using that book so don't buy it," followed by twenty groans. These days it is computers telling you what books to buy.)

Textbooking is kind of a racket---a good deal on one could bring the publishers millions.

I don't think that the frustrations have changed substantially.
