"And, besides, unlike Matt, I have run cassette-tape
based operating systems so I can pull geek seniority rank over him.
Just call me Sid Dabster. Before jumping into my own list, I should
say up-front that not all these systems are dead, or really even
obsolete. My first two, OS/2 and NeXTStep, actually live on in
evolved versions. 1) OS/2 Warp - Put aside all the fan-boy ranting
about it was the greatest thing since TOPS-20-and if you get that
reference, congratulations you really are a fellow operating system
geek-OS/2 really was a great, solid 32-bit operating system., when
everything else running on a PC was 16-bits."
