Hmmm. I hadn't come here looking for an argument (or abuse, those are other rooms altogether), but I found this to be an interesting take on my comment.
I value the environment as well, but given that a lot of what I read would constitute pulp fiction (literally - ha!) there is something to be said for recycling efforts, use of sustainable source forests and the like. I'm no paper industry shill and I'm sure as a whole they're responsible for a lot of pollution and resource consumption, but hopefully not as much as in the past.
Moving on to D and E there, I agree that in many cases, ebooks are fantastic. But my problem, as stated above, relatees to ownership and physical media. Not having ownership in many cases is a big problem for me. And I personally like perusing the stacks at a good library or book store. I read to experience things I can't otherwise do, and in many cases, because of how some of my reading selections tie into friends' recommendations or common activities, the reading or discussion afterwards makes memories too.
I value the emotional responses I feel from a good story, and I enjoy a good "popcorn Saturday" kind of book too. I know I can have that with ebooks, but the experiences surrounding them aren't the same. If I truly felt that ebooks would go ina direction allowing true ownership and fairly open/compatible standards for the readers/clients, I'd be much happier. but I don't believe we'll get that utopia. Not with the legacy business model mindsets at work...
And speaking of legacies, I've been working on a small collection of "personal touchstone" works in sci-fi, fantasy, and a little romance. I hope one day I can pass them on to my children. The older ones actually read a fair bit, and the baby will hopefully grow up with equal access to either media.
