I love this.
Ebooks would be fantastic to use at school, particularly if you have some form or smartboard or interactive whiteboard. Imagine using picture books for Infants students or as a tool for visual texts in highschools. We could use them simply as a reading tool.
I also love audio books, I already buy and borrow audio books from the library. The ability to download them and to listen to them in my car on my 1hr drive to work and home is fantastic.
Happy Reading =)
