Are you trying to convince me I'm wrong, or asking why I would prefer hardback books? Softbound books don't hold up to heavy use at my table. I have 30 years of gaming experience to tell me that's true. Not only that, you are completely out of touch if you think they could sell a soft-cover AP for 5 bucks. My Shackled City hardcover is over 400 pages in full color - there's no way you could sell that in physical form for less than $25-30 unless it's printed on tissue paper. The other option, purely digital, is another canard. You're proposing they could sell a 400 page PDF for $3 and somehow still be able to pay the authors, artists, editors, and the rest of the staff. Even after that, I'd have to spend $20 of my own money just to print the thing. I'm not seeing anything even remotely feasible in anything you've suggested.
