Well, for one, sometimes you need to do a port scan when you're not in
front of a system that has nmap installed on it.  I get a call about
once every couple of months, "why can't I get into my email server"
that's sitting behind a hardware router with a hole poked in it for
port 110.  Doing a port scan on the client's IP address ensures that
either yes, the port is open or no, it's not.  If it's open then I can
proceed with my troubleshooting - if not, I know where to look for the
problem.
