With textbooks, one tends to move back and forth through the pages, referring to different sections, which is why I don't like digital textbooks.

This. DD isn't allowed to bring home any textbooks, but we can refer to her math book as an online text. It's a clunky interface, which doesn't help, but for me online textbooks are just a drag. It's the same reason I don't buy ebook versions of cookbooks or reference books. I want to flippy flippy fasty fasty. I don't know--maybe the interface just needs to get better, but I can't be the only one who prefers the physicality of a book in these situations? DD didn't like the digital book, either, for all that she is supposed to be a digital native or whatever.

I do love my ereader, mind.
