The average tablet owner simply does not always keep their apps up to date. In your circle of friends, there is always one person who seems to have always have a thousand emails in their inbox or never updates their apps. This is the Amazon update that you should install because it preserves all of the books you have downloaded on your device. If you update to iOS 7 and don’t update the Amazon app you have to download all of your books again.
