You can find personality in almost any computer
subculture if you look
hard enough. I've been involved with the "demoscene" since 1990 and no
matter what platform a demo is written on, there's a lot of personality.
I'd argue that IBM machinery definitely had a personality -- reliable,
solid, strong, definitive. Artistic or creative? No. But intriguing
all the same.
Um. Can you say "OS/2"?
OS/2 has a personality. What kind of personality is up to debate. ;-)
