...Like audible.com, or something similar, and implement it into the iBooks App. I was just thinking how convenient it would be if you bought a book in iBook's store, and had the option to read it or listen to it on your drive home, when you have to keep your eyes on the road. The real convenience factor would be that you could get both versions with one purchase, and they were "bundled" together. Then, when you were reading during your lunch break you could bookmark it where you left off, and when you're driving home, you could listen to the audible version continuing from where you left your book mark. And vise versa, so it automatically book marked where you quit listening to the audible version and put your bookmark for the "print" version in the same spot. I know that some people don't enjoy "listening" to books as much, and others hate reading but they like stories so they have gone to almost completely using audiobooks. So not everybody would want both. In that case, you would have the option to just purchase one version of the book. If you changed your mind later, and wanted the other version too, you would have the option to purchase it separately and they would still "bundle" themselves so bookmarks would work. To purchase both at the same time, there would of course be a premium price factor, but it would be slightly cheaper than buying both versions separately.
