If you read email you need selinux. If you read email with a client that
fires up plugins to read special content (e.g. html, pdfs, flash) then you
really need selinux.

If you use a web browser to view more than a short list of trusted sites,
you need selinux.

If you run network services accessible from outside the machine then you
need selinux.

If you run binaries from semitrusted groups (this includes most commercial
software) then you need selinux.
