Walter Isaacson’s Steve Jobs biography has surfaced as the top-selling book on Amazon.com, per the online retailer’s Best Seller in Books for 2011 listing. Mind you, we’re talking about best-sellers for the whole 2011 here. Remember, Isaacson’s book has been selling for two months barely. The bio was released on October 23, a little over two weeks following Steve Jobs’s passing on October 5. It’s available as a digital download in Amazon’s Kindle Store and Apple’s iBookstore, and in hard cover form at bookstores worldwide.
