I read the first few pages of Lee Smolin's book and I'd say he goes a *bit* farther than show the flaws of String Theory. From the introduction, it looks like he trashes the whole model.
I stopped reading that one once Feynman's book QED came in from interlibrary loan... and all I can say is "wow." It all makes sense now! Feynman is officially the best guy ever now
