Hands on: iBooks Author effortless to use, but iPad-only | Macworld: iPad-exclusivity aside, those willing to work in iBooks Author should be quite pleased. It’s the best WYSIWYG ebook designer I’ve seen on the market so far, and—formatting problems excluded—incredibly easy to work with. If you have iTunes Producer installed, you can even use the Publish button to send your finished book directly to the publishing process; you’ll still need an ISBN and an iBookstore sales account to proceed, but it’s a nice link to unify the process.
