small business operationsLinux with hardware disadvantage
supported a community of users 3 times size of NT’s

System Administration – Most significant differenceLinux – tougher environmentLinux requires learning multi-user issues built into
Unix-file permissionsNT – easier environmentNT requires less effort to get a starter server up and
runningBut in NT you have to solve multi-user issues for
each and every subsystem

In The Commercial ArenaIn The Commercial Arena
NT – graphical interfaces, wizards and easy-to-grasp metaphors
But as server chores become more customized, NT cannot handle it
Linux – textual interface (with X-Window)But for complex jobs, Linux gives a powerful
set of tools

ConclusionConclusion
“When is it best to use Linux and when should some other operating system be preferred?”
It all depends on the user
