Who ever thought this day would come?!? J.K. Rowling has finally allowed the Harry Potter books to be read digitally. According to the FAQ it's in conjunction with the Pottermore launch. So, go sign up on Pottermore and then buy your Harry Potter collection so you can stop hauling those books around like you have for the last decade. Or order a new set for the kid who isn't going off to college.
