An article on second-hand sales of video games

made me understand another reason when eBooks are worth less than paper books.
There's no second-hand market for eBooks. Not even for non-DRMed eBooks. Why not? Because I can't get rid of my copy of the eBook. Even if I copy it onto a CD-R and wipe all copies from my computers, I still have the eBook -- sitting in my bookshelf at fictionwise.com or webscriptions.net.
So - if I buy a paperback or hardback, the book retains some resale value. This makes it more valuable that the equivalent eBook.
eBooks should* always cost less than the paper edition.

*OK "should" is problematical. Things cost what people are willing to pay. I think that in the long term, people won't be willingto pay as much for an eBook as for a paperbook. If publishers keep trying to sell eBooks for as much or more than the paper editions, they won't make significant eBook sales.
