Apple unveiled its plans to revolutionize educational publishing with the release of iBooks Author, iBooks 2, and iTunes.
The first E-Textbooks are already available through the iBooks store from Pearson, McGraw-Hill and other educational publishers. The books include video, photos, narrations and other interactive material, all of which is downloaded in a single package to the iPad. A biology textbook from McGraw-Hill contains 1,906 print pages and weighs in at 1.49 GB, while a competing Biology textbook from Pearson contains 1,791 pages and weighs 2.77 GB.
The content presumably is downloaded once over Wi-Fi and stored locally on the iPad, as well as being archived on iCloud.
