It's official, Apple with be changing from the current PowerPC (IBM) architecture to Intel's x86. Personally I can see this causing a lot of issues with the software we have developed and are developing. As we are using Macromedia (Adobe?) Director I don't have the luxury of just recompiling our software, I'll have to wait for an update to Director before that happens. Of course what about our older software that was built in previous versions of director. As most Director developers know it's had some major syntax changes in the current version (MX 2004).
I guess the only thing I can do is wait and see what happens, you never know it might cause the end of the Macintosh and save me a lot of development/testing time (but I doubt it).
