Never needed audio, but until Apple dumped Motorola and went to Intel chips Apple was the best for me. OSX is a convoluted piece of crap that should have been trashed before they ever released it. And the later the OSX is, the worse it is. I hate when people fix what is not broken, then have a piece of junk that IS broken with no plans on fixing the broken fixes.
The only redeeming grace for Apple is that OS9 would still work on early Intel machines. When possible I always use OS9 even on a G4 dual processor mirror door with firewire that supposedly will not run OS9. That machine runs rings around all of my other G4s which were designed to run OS9. Need to find another one and replace this slow G4.
As far as Windoz is concerned, it is worse than OSX. I avoid it whenever possible, however, I do have a Windoz machine that I use at home when I cannot use my Apples.
Sooner or later, if I live that long, I will be forced to move away from OS9. No idea where to as I see NOTHING worth spending a decade migrating to.
