The online book is a widely used method of presenting, for example products. But this is not where its potential stops, have an online manual created for your product with installation or assembly instructions, guestbook, newspaper, etc., it's only your imagination that limits the use of this product.
This product don't even have to be online, use it as a derivative of your own product, use it on a CD as an executable file and use it to present products, idea and other materials at meetings or maybe just to spice up your sales emails.
Because this product contains flash elements from the start and therefore is not mobile compatible, but that makes it possible to exploit the increased amount of animation the product may contain.
