Hi. This question may sound a little vague, but just wanted to know if based on your experiance you can provide some suggestions on this.
We are having a requirement to build a very big and Rich UI desktop native application. Also we need live data to be available on application all the time. Which technology would be better to use for such application:
1. Sencha EXT JS and Sencha Desktop Packager
2. Flex code and Adobe AIR.

Please note that we already have full application developed in Flex and running on Adobe AIR. but now thinking about moving UI from Flex to HTML5 and JS as Flex is no longer supported by Adobe. Is this a wise idea?
