Central was a framework that you develop flash modules for that could access desktop resources. This meant that although you were "breaking out of the browser" you were also breaking into the Central Framework UI. There were all sorts of licensing issues on top of the fact that you couldn't develop a completely custom branded user experience.
Although some of the guys who worked on Central are also working on Apollo Adobe have reassured developers countless times that Apollo is NOT Central 2.0, e.g: -
There were lessons learned from building Central, and from users using Central, but this is completely new, and built from the ground up. Apollo does not share any of the Central code base.If you don't know what Apollo is then go to http://labs.adobe.com/wiki/index.php/Apollo, the rest of this post kind of assumes that you have an overview of Apollo.
To summarise the video, Apollo allows developers to: -
- create Flash/Flex desktop applications;
- create Flash/Flex/AJAX desktop applications;
- create AJAX desktop applications (no Flash required);
