I chose Flex 4 as the most appropriate technology for developing a graphically rich web application (its not just a website focused on content), but was worried about how the recent negative press (i.e. security issues) user trust and, ultimately, could whether the user base quickly discard the answer. (I don't care if my application works on iphones or ipads)
I think Flash Builder 4 is a great development environment and minimized development time for me / my team. After some basic testing of graphical animations, similar to the one used in my application - HTML5 did not run so fast, it is incompatible with browsers, and some animations are jagged (I expect browser performance and graphics libraries to improve over time). I also personally don’t like Javascript programming, as I really like strong typing to quickly spot errors.
If you are developing Rich Internet Apps, how do you respond?
Are you ready to potentially migrate to HTML5 / Javascript? Java? No action?
BTW - I don't need pro / anti-flash arguments - just curious to see how the community responds.
At the end of the day, Flash / Flex is here to stay. If Flex 4 meets your current needs, and you are aware of the limitations (i.e., you cannot deploy them on iOS devices), then I say that you need to go for it. Yes, it’s true that the topic has become slightly politicized, but if you offer something that your customers need, then it would be foolish to refuse to use it on the grounds that they support “HTML 5” - when HTML 5 does not explicitly offer the necessary you tools.
A lot of awesome things are being laid out in Flash, many of which are simply impossible to do in any other way - for example, Google UJam. I would not let Steve Jobs scare you away from using technology that works for your needs.
