I don't read as much as I used to, and when I really think about it I get regretful. I definitely read more than 1-4 books/year, but I just don't have the time to devote to it anymore. I strongly prefer actual books, but I've been doing a lot of reading on my iphone over the past few years due to being able to read when I have spots of downtime (waiting on oil change, for example).
