My reading has pretty much become completely digital. Both novels and comics, I buy digitally. The only exceptions are things like A) artbooks, and B) graphic novels I enjoyed very much, to the extent that I'd like a copy on my shelf. But only in a deluxe/prestige format if that exists.I don't disagree with that. I just mostly think it was smart of them to sell e-books, and they are still doing that. Personally, I have a Kindle, and it certainly has caused me to buy fewer (but not zero!) physical books. Mostly what I don't physically buy anymore are cheap (~$5) trash scifi/fantasy books. Those things are taking up too much space as it is.
But anyhow, my main point was that if B&N went straight to the app instead of trying to develop their own hardware, they could have saved all that money and still exploited the ebook strategy.
