I think you might find this article interesting for this discussion: "After 6 years doing Flex, am I moving to HTML5?": https://plus.google.com/109047477151984864676/posts/CVGJKLMMehs Bottom line: when working on enterprise RIAs, I would lower my expectations on finding a viable alternative to Flex, at least for the next two years. In the meantime, either you cut on the requirements and UX, or simply stick with Flex. JS
