Might I recommend http://tent.io http://tent.io as an alternative? I don't have any affiliation with the project. I just think it's the brightest option I've seen for the future of the consumer cloud. It's basically a cloud backend protocol that allows the customer to pick their own tent host that acts as a data store for content they create at sites that use it for a backend. They can even host their own tent. The point is that it gives the user power over where their content is actually stored, with the benefit of centralizing content from disparate apps.
