So, it appears that Adobe is transitioning Flash from a tool used by web developers to a tool for app developers. With Adobe AIR, you can build from a single source code, an app that runs on the desktop, iPhone, iPad, Kindle Fire, Blackberry Playbook, Windows 8 Metro, Android phone, etc…
Very few other technologies come close (.NET/Mono can be used to build it with mostly the same code base, with a different UI layer)
The future of app development will be interesting.
