I am also a very slow reader because I love to immerse myself and take my time. I'd average between 30 - 60 books per year (the number has gone down since I started getting addicted to TRYING to learn to play a couple of instruments as well...). As for ebooks, I'd say the average is currently under 5 per year. I'll see what happens when e-ink hits Australia properly!!
