It's funny, as someone who grew up with books and the burgeoning world wide web, I hadn't thought of this. When I'm learning a topic I tend to buy or print books so I can soak it in. When I to learn a quick task I go online. Books tend to be great for the why's of something but not the how's. Online is great for the how's but not the why's. I think a blended approach has ended up being the best way for me to learn. I do have a genuine love of books though.
