I really like how both Starling and Feathers have proven to be great platforms for non-gaming applications. If you can do games, you can do anything! My client was really impressed with the multi-platform performance, so it wasn't hard to convince them to use these libraries.

I started a professional tablet application based on Starling and Feathers, and these libraries save me a lot of time and pain in the development process. The app runs very smoothly on all platforms, including Android tablets, iPad, and Windows 8 Pro tablets. That's simply awesome.
