Being about the same age as it, and only dreaming of having a computer for most of that time, I didn't get a chance to see the OS/2 in action. But what I do miss about it are the jokes, which are just about the only relation I have with it. Jokes like:
OS/2 VirusScan -- "Windows found: Remove it? [Y,Y]"
Windows vs OS/2 = Michael Jackson vs Mike Tyson
OS/2... Opens up Windows, shuts up Gates
Microsoft gives you Windows... OS/2 gives you the whole house
Is OS/2 half an operating system?
And many more. Now, all I've got are Mac jokes.
