An interesting essay by digital media pundit Nicholas Carr on the slowing pace of ebook adoption--one I admit to favoring because it pretty much tracks my own ideas about the ultimate place of the ebook in our media ecosphere.

E-books, in other words, may turn out to be just another format—an even lighter-weight, more disposable paperback. That would fit with the discovery that once people start buying digital books, they don't necessarily stop buying printed ones. In fact, according to Pew, nearly 90% of e-book readers continue to read physical volumes. The two forms seem to serve different purposes.
