For novels, or short-stories, I'm old-fashioned and have a hard time moving away from my preference of physical, printed books. I do acknowledge the benefits of e-books though, such as being able to store a virtually infinite number of books, built-in dictionaries, note-taking capabilities, and perhaps most interestingly, the potential for social interaction between readers as they read it. Plus, e-ink screens are surprisingly comfortable for my eyes to read on, and the backlit ones eliminate the problem of it being too dark to read. For articles and things that I can read in just a few minutes I prefer my phone. It's always on me, the screen dimension is pleasant enough, I can easily share/save it for a later time, etc.
