Fascinating how a thread that was introduced to denigrate Microsoft has provoked so many defensive responses.
I was using OS9 on 68000 based computers before Linux existed.
Minix was around, BSD existed on college servers, and Microsoft was still pushing Xenix.
But the Mac crowd was using a graphic based OS with no command line (on a black and white display) and X86 machines were running a criude CLI based OS that was basically a copy of CPM.
So now, two decades later, you young punks think you can educate ME?
You're just using systems that have finally caught up to ideas I was advocating in the 80's.
