So, maybe the Kindle beats the iPad as an ebook reader (although, at $140, I could justify a Kindle now and still buy myself a second-generation iPad next year), but with the iPad, things like this are available to a mass audience with a couple clicks:
One example is the ‘Enhanced Edition’ of Nixonland, by Rick Perlstein, a chronicle of our 37th President. The book contains the full text of the book first published in 2008. It also includes 27 videos of the former President and newsreels that put those turbulent years into perspective.
Or things like this:
Civil War: America’s Epic Struggle (US$4.99) from MultiEducator Inc. is a full history course in an iPad and iPhone app. It contains at least as much information as most textbooks on the Civil War at a fraction of the cost, while adding elements that no textbook can. There are 24 multimedia presentations, some as long as nine minutes, a nice selection of music popular during the Civil War, and a wonderful navigation system that just makes sense.
