For what it's worth...
I usually read at least four books at a time. I read a conventional book (usually a paperback) at work during lunch. I read an e-book on my Kindle or phone for when a conventional book would be too cumbersome. I listen to an audio book on drives or when I'm working out or "running". I read a conventional book at home in the evenings (usually a pulp sci-fi or fantasy series book).
