I'm the same. I think it's important to use both resources. Some material in books is, as has already been said, not available online, and my university requires me to gain references from both print and digitised material for every assignment I produce, regardless of my own preferences. The Internet is certainly helpful in its broad provision of current information, but I do think that this information needs to be filtered with the knowledge gained from books, in order to gain a comprehensive understanding of the subject. However, I do love reading, and am therefore likely slightly biased in its favour.
