Keynote and Creating ebooks

I found what I thought was a pretty good, and concise manual directed towards teachers on how to use/navigate Keynote. As the author says, you can download the nearly 200 page user guide but the reality is that most users will not need that much information. I also liked the visuals that he added to the pdf making it much easier to follow. Have a look and see what you think.

I also tried making a quick ebook using Keynote and found that the only drawback was not being able to create and insert audio within the slideware. Instead I needed to use GarageBand and iTunes to record and insert audio through the media inspector creating an extra step. Not a terrible inconvenience but if all I want to do is narrate the text I believe that PowerPoint has the edge on function.
