Still I think ebooks are a different product. At least in my head. I have a different emotional relationship with a physical book. The information within isn't in competition with the endless a "wealth" of information available legally or not.

For text books piracy is a victimless "crime" in my case, as having a digital copy or not, is independent from financial loss above a certain price tag. That is, I can't afford most text books, so I won't buy them; piracy does not influence the income of the publisher. On the other hand, if I really need/want to buy a book, I am likely gonna get much more intimate with it. Let's face it, digital copies are much more likely not to be read. Maybe only indexed and searched as part of a collection. Digital has a different value. (Although, I ofc understand the superficial dilemma here.)

This is the situation we got IMO.

Side note: You, as someone from the industry, I assume we can both agree that at the very least, a free digital copy should be included with every physical one, right? That just silly and artificial to separate, if you make an argument for the value of content and presentation.
