The document discusses developing mobile apps for MeeGo using Qt Quick and JavaScript. It outlines a 3 step process: 1) Set up a development environment with Qt Creator IDE and emulators. 2) Use Qt Quick's declarative runtime and JavaScript bindings for advanced graphics and animations. 3) Leverage JavaScript to build rich mobile apps by importing files, using expressions, and binding to QML. An example Angry Birds-style game app is demonstrated.

- SLIDE 1: There is a very REAL Mobile Apps Opportunity -------------------------------------------------------- 2010 - xyz Million $ -> 2013 - abc Million dollars 2010- Growth Distimo report
- My Goal for the afternoon is to Show you 3 things -------------------------------------------------- 1. Tools/SDK/Devices for MeeGo Development are available TODAY QT SDK, Qt Creator, Complete IDE, QT Quick, Designer, and device N900 2. Fun to Create Cutting Edge Graphics and Animation using QML With QML states and Transitions its so easy that it is fun 3. Easy to develop Feature rich Mobile App using JavaScript These three tools will give you the power to create cutting edget Mobile Apps for MeeGo TODAY But Before I jump into the interesting part let me give you a context
