AIR1 v AIR2 v Spark

[Rufus McDufus]

Going back to AIR1 vs AIR2, I *think* AIR1 was software more natively tailored for Mac, probably compiled C/C++ hooking into the OS's libraries directly. AIR2 is based on the QT framework which gives them portability to other operating systems and more rapid development time, but on the downside leaves them exposed to any bugs or problems there may be in the QT framework's libraries, method of compilation etc. And AIR being a fairly atypical application, it's not totally impossible they're doing things with it & placing requirements on it that not many developers have done before and I suspect they're finding problems as a result. A similar thing happened with Linn and the Mono framework for Kinsky - they were stuck & powerless on waiting for the Mono developers to fix problems in the framework.
Just a hunch of mine but I've seen this situation quite a few times.
