Looking for a bit of light reading this weekend? Then look no further than the 400+ pages of the Economic Report of the President (the hotly anticipated sequel to the Economic Report of the President) which, for the first time, has been made available as a free e-book. That includes versions ready to be delivered to your Kindle or Nook (the former of which is already sitting at #46 on the bestseller list), and an ePub version for Sony readers and other devices. Will this be the final step that truly pushes e-books into the mainstream? Probably not. But if this rapid adoption of technology by the White House is any indication, we could well see weekly Presidential addresses in 3D next year.
