TED Books is an iPad app that provides TED fans with short electronic books produced once a month by TED conferences. The books are less than 20.000 words long "long enough to unleash a powerful narrative, but short enough to be read in a single sitting." Here is what the folks in TED said about this app :
The TED Books app allows us to embed audio, video, and social features into each book, broadening the depth and detail of each work. These additional multimedia features suit the wide-ranging creative palette of our contributors, many of who use photography, audio, and video in addition to the printed word to fully express their ideas.
TED Books is free to download but you need to pay to buy books. The price of these books ranges between $1,80 to $5 . The titles I bought are : Mind Amplifier (by Howard Rheingold), Why School ( By Richard Will ), and Homo Evolutis ( by Jaun Enriquez, and Steve Gullians ).
