Thanks for your reply. So if I buy Pages is it going to provide everything needed to publish a book on iBook Store? e.g. Am I going to be able create an ePub file with my book cover on it?
If you say that a casual user like me can handle Pages for this task it would be great as it is not that expensive.
I know Indesign, it is very expensive and professional, dont think it would be suitable for me.
One last thing: If I use iBooks Author than I had to publish my book ONLY in the iBook store, right? I guess that is why you did not recomment it to me.
Pages generates epub. Beyond that and the link I gave you already, best search/ask in the Pages forum.
iBooks Author does not do .epub. It generates a special format, .ibooks, which can only be read on an iPad (and can only be distributed via the ibookstore if you want to charge money for it).
