Ebooks solve specific problems that paper simply cannot, the biggest being that you can carry an entire library in a package smaller than a typical paper book. Beyond that, ebooks can be acquired immediately, and many vendors allow you to sample the book prior to reading. All that said, I've also returned to paper for essentially anything I anticipate wanting to take more than a few notes in, or really referring back to at all.
