I need some insight into PaaS from a developers standpoint, where would you like to see it go? What are its limitations? Are the providers of PaaS different? Or do they offer the same features but just name them differently?

For myself, I'd like to see PaaS become sophisticated enough to create 3d or graphically pleasing applications, I think thats what sets applications apart from each other, the way they look, and feel, and the type of user experience you get from them. Those can all be enhanced by a rich interface. I understand that generally depends on what API's or what programming language you're using, but the beauty of some PaaS providers is that programming and coding isn't necessary, so somehow that needs to be combined with a way to develop visually stunning applications.

Unless I'm missing something...
