If you buy a physical book, it is yours to resell if you like. The same may not be true of e-books. What do you think the implications of this are for the future? Should e-books be treated more like regular books, with the copyright owner's rights to control sales be limited to the "first sale"? Or is the author's ability to restrict the full powers of other's ownership interests in the book a good thing for society?
