HaXe is revolutionary, people who really try it always seem to stay with it, they just have to get past the ask lets of questions and actually try some code and stop being negative and putting it in the less able solutions pile. If you want to waste days coding a game in pure objectiveC and then converting it to java just to target two phones then good luck to you! And if you code something in one language it should just be a case of switching some target specific libraries and all your work now works in another target, not recoding in another language style. HaXe is revolutionary because it in achieving what other solutions promise but normally fall short on providing - cross platform cross language, code that is designed to enable not fragment. So try it rather than assume!
You don't have show stopper issues with the compiler ( it outperforms flex compiler on flash target ). Any minor issues are often resolved within hours of reporting, unless they are language design decisions rather than bugs.

The forum is not well used as most users use the googlegroup 'haxelang'. In terms of frameworks like flex, haxe for flash target does not support flex well, it can be made to work, but largely the problem is because flex is not really just actionscript but has some adobe secrets/hacks etc.. that is why it has not been ported to a cross platform solution yet, need some better engineering decisions although someone I think is working on it. In terms of other frameworks for components there are some but they could be better, try aswing, feel free to chat on IRC if you have problems getting a particular component framework running. Generally haxe is sort of tool that you can build from scratch your visual interface stuff, or if your using js you can mix it up with native libraries.

You can add any support for mobile camera's or video you want it interfaces easily with c++/c and there is java support and there is openframework support try this site http://blog.onthewings.net/. Haxe is not really a game only language but it excels at allowing users to create visual stuff but still do complex game mechanics, and a lot of users enjoy doing games. It works well in solving the issues of having to mix technologies, being normally a more sane programming language than the target but also mixing well, so you can mix haxe php, haxe js and haxe flash ( http://haxe.org/doc/remoting ), or use NME library to hit all the phones and have a web version in flash for users to try online.
