Apple has updated the iBooks application to now support the embedding of audio and video content into digital books. iBooks, of course, now runs on the iPhone and iPod touch, in addition to the iPad, all courtesy of the iOS 4 update.
Apple Release Notes:
- Double-tap an image within a book to view it in greater detail.
- Experience books that include audio and video.
- Enjoy substantial performance improvements when reading PDFs.
- Look-up definitions to English words inside books without a specified language.
- Addresses an issue that may have caused some book downloads to not complete.
- Includes many stability and performance improvements.
So, it seems this update is meant to angle the iBooks application as more than a eBook reader, but instead, the possible reinvention of the book as we know it. Just think, a instruction manual with a built in how-to video, or a embedded sound file with the correct pronunciation of a fictitious word. The possibilities are endless
