I'm very interested to hear what others have to say about this as I've been doing some research since I'm in the process of writing a book. I've already accepted that I'm going to have to pay and I'm ok with that since this is a tool I plan to use frequently - since I'm making a customized book.
I know there's a ton out there - that's why the decision is so hard in which one to go with! I don't need video capability in my book and I'm not looking to do any live animations or anything crazy. I'm just writing an "old fashion" illustrated book ;-)
If anyone has has recommendations/experience in using this type of program I'd love to hear from you!
