First off, I'm not arguing with you. :>

* In a message originally to David Wright, Kevin Lowey said:
KL>Actually, this isn't quite true.  The entire file system is
KL>designed with multiple users in mind.  For example, each file
KL>has a Read, Write, and Execute permission on it for the
KL>Owner, Group, and World.  That means you can set up files in

So does LAN Manager/Server.  And many more, as well as any possible 
combination of security flags.

KL>Unix has support for quotas on individuals.  You can say Joe

KL>jobs at a priority higher than X.   Joe can only access these

KL>print to the printer, but he cannot get access to the modem
KL>to make long-distance calls.

All of these functions are available with LM/LS today, with the exception of 
CPU usage tracking.  And Citrix has the same functionality as LM/LS as well, 
only routed through DigiTalk boards to dumb terminals.

KL>There is much more to being multi-user than just having more

KL>better suited to multiple users than OS/2 is.

Absolutely.  However, Unix is 20 years old, while OS/2 is only 4, and LM/LS 
is only 3.

Also, UNIX was designed for supporting dumb terminals, while OS/2's first 
priority was supporting intelligent CPUs.  The guy who owns Citrix was the "
father" of OS/2 at IBM, and he swears up and down that it was designed to 
support multiple users...
