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).
