Engadget: You didn't think Barnes & Noble was just going to let Amazon rest on its "vague sales milestones" laurels, did you? The veteran bookseller just announced that the Nook lineup -- 3G, WiFi, and the new Nook Color combined -- has become "the company's biggest bestseller ever in its nearly 40-year history." That's bigger than Barnes & Noble's sales (note: not global sales) of DaVinci Code or any of the Harry Potter novels.
