Inspirational, but..
Apple has created a winner along the lines of Keynote, Pages and iWeb. But why the builders of this App have failed to provide for an interactive TOC? Imagine an ebook that wont allow you to touch on a chapter or page title in the TOC to take you there! Many Apple discussion group posts have pointed out this flaw.
I, too, find the templates too rigid. Landscape format books have a vertical divider down the middle of the lead page of each chapter. Cant get rid of it.
