Pro Sideloads on any Android device
It's not just for Kindle.
The Amazon Appstore gets exclusives from time to time such as The Wolf Among Us or République. Though some of the exclusives are also tied to their own hardware such as the HDX. Not only is this a good incentive to purchase Amazon Android devices, but it also shows a commitment to feature hardcore games on their app store.

Con Apps can not be used if store is uninstalled
Any app installed from the Amazon Appstore will not work if the Amazon Appstore itself is uninstalled. this is basically a DRM system where in any app from the store will not work if the store is not installed.
