這個hero 不是htc hero 呢~，乃是 flex sdk 下一version。

經過4個version 之後，flex 都開始變得穩定，

* Multi-Screen Development: Allow developers to build applications that target the web, desktop or mobile devices using a single unified framework.

* Spark Maturation: Polish and grow the Spark architecture by adding new Spark components and capabilities. (Spark Framework 由flex 4 引入，下一個version 當然會加入更多spark 的新 components 和 features

* Large-Application Development: Support developers building large applications by improving fundamental pieces of the Flex infrastructure.
