The iPad is getting some serious action as a children’s toy, courtesy of various games and books-at-apps that are actually popular enough to hit the top 25 list of the app store in some countries. Apple has apparently taken note of this and has introduced a new feature in iBooks 1.3 where certain books have a read-aloud feature. We’re not talking text-to-speech, but rather an audio book included in the book purchase. SOme books will even highlight the words as the story is being read, helping kids to pay attention and learn to read themselves. The feature is only available on select books and naturally only in countries where the iBooks store have paid content. The update should be available for those who have iBooks installed, or you can download the app from iTunes.
