That book about Starbucks

Has anyone read that new book, 'Starbucked'? (I haven't). The writer had a piece in Slate this week specifically about how more independent coffee shops have opened up around the nation since Starbucks became big, and how on a local level having a Starbucks in your area helps the little cafes. It all sounds a bit far fetched, but if there's a trick in those stats he presents, I can't think of what it would be.
