You know how Apple is always calling its products “magical?” Well, it turns out that it may be right. Harry Potter author J.K Rowling not only uses a MacBook Air to write, but says that it has changed her life.

J.K. Rowling’s enormously successful Harry Potter series is about an incompetent orphan who lucks his way through a series of magical adventures despite being essentially inept. Tens of millions of people — myself included! — have enjoyed them over the course of the last decade, but only in dead tree form. Bizarrely, Harry Potter has never officially come to e-books up until now.

Of course, no longer. As one last magical trick, Harry Potter has made the jump to a number of e-book stores, including Amazon, Barnes & Noble, Google and Sony. The only company left out? Apple’s iBookstore.
