Third, Apple originally touted OS X as a very open Unix like variant. They had all sorts of technologies that were there to draw developers and Windows users to the platform. Built in Java and C/C++ APIs as first class development language along with Objective-C. As Apple became more comfortable with their position and had less fear of Developers being unwilling to move to the platform, the first dropped Java as a first class language (no more Java-Objective-C API bindings) two years ago, and last year dropped the C/C++ API's further development.
The net result of this is that if you want to develop a native 64 bit GUI application on OS X, you must use Objective-C. ObjC is a fine language, and now has Garbage collection, amongst other things, but it is very very difficult to port ObjC applications to other platforms. In a way, it's like Microsoft's .Net, except that there's not even an ObjC Mono to counter it.
This means huge costs of major software developers who have, for the most part, been developing in C/C++. Microsoft Office, Adobe CS3, Maxon Cinema 4D? They're all C/C++. There will be no 64 bit version of Adobe CS4, the next CS iteration, for OS X, Adobe has said. It will literally take them years to port their code base to ObjC. Personally, I wonder why they bother. Given that the Ubuntu Linux desktop is now very smooth, is getting fantastic reviews all around the net on mainstream publications, It would be a perfect time for Adobe and others to port their apps to Linux (with far less effort and far lower cost than porting to ObjC). Putting some of the money saved into a major marketing push for Linux would help the uptake.
I mean, aren't the updates every 2 years or something? That's 2010 before I can get my hands on CS5.
