One word: AWESOME.

The Astonishing Tribe is a company that develops user interfaces and is damed good at it:

Arguably, these user interfaces are a little flashy, but they have tons of great ideas that could be effectively used if implemented well. It seems like they support MeeGo and Android, and here's to hoping that more developers use their awesome frameworks for app development.

Were I a mobile app developer, I wouldn't hesitate to use these frameworks for my apps. They are INCREDIBLE and are a definite value add (if only just for visuals).
