Err yes, I understand and want to apologize with the MOS friends out there. The points is quite complex: I do some programming on multiple targets (Posix, AmigaOS 3, MacOS Classic and, as soon as the G5 is out, Mac OS X). Testing software is already a horrible task, now imagine having to deal with subtle differences, GUI aspect and behaviour, kernel timings and so on. Imagine keeping the source trees up and running on all these systems!
so when I say that I will not run both AOS and MOS is because since they share the same API, I expect them to run the same software and possibly tha same way.
