Owning a library has a higher value than owning a library of ebooks: social, decorative, nostalgic, works without power, easy share, can resell, etc. It more than evens out. But there is Steam effect - people will stockpile ebooks they don't read.
This is subjective and not monetary value. The only people that care about social, decorative, and nostalgic value of books are also the people who probably wont resell books.
> works without power
finding a place to charge your device is easy and ereaders last months without recharging
> easy to share, resell
Sure but the money you save by reselling a book is probably less than what you save by buying the ebook
Space and weight are real, expensive costs. Owning a library has negative monetary value. Owning a library of ebooks doesn't. It's stored on the internet and you can access it from anywhere.
Basically, if your books aren't furniture and you aren't sharing your books multiple times a month ebooks provide more value.
This is what I had hoped for when Kindle came around and Amazon started pushing Ebooks - but unfortunately it just isnt true. The difference between ebook and paperback is currently low enough that if you maintain your paperbacks well - you'll still end up spending less (net) on the book - in quite a few cases. (Heck you can even resell the paperbacks using Amazon ;))
Not under the publisher's model.
