I started taking notes of business books in a "books" journal in Evernote. It's MUCH slower to read but I can (and do) go back to my notes to solidify concepts or cross-check them with things I read in other blog posts or books. I find it also helps retention, by taking notes, I'm really focused on understanding what I read and how it applies to past challenges, current ideas etc. On the other hand, there are books I've read this year for which I don't have notes if I read them on the kindle (in the subway for example), and then it's much harder to remember what it was about and how I can use it in my life. So: take notes.
