Love the idea of these cloud based services and I also like the idea of a content management app that does not want to try and take over your application. However outside of personal projects at work I am scared that these cloud based blackboxes at the heart of my applications will mean that I have no control of bad performance, releases of their software or unplanned downtime. I wish that people gave me the option for a self hosted solution as well as the cloud (that was not a ultra premium we do not bother listing it on the website package)... plenty of enterprises are still self hosting.
