My reason for recommending a router even for a single computer system is
that I think it's a good idea to run your firewall on a separate box. That
way if there is a bug that could lead to a buffer overflow exploit it
doesn't immediately leave the attacker in control of your box. Routers are
also incredibly easy to configure, they all use nice and simple browser
interfaces. They also act as a firewall to the clueless support people at
your ISP. If you use the word Linux to them they'll crawl up into the
fetal position and start sucking their thumbs. If you use the word Linksys
they'll be happy. Finally routers are dirt cheap, the wireless ones are
around $75, the basic ones are under $50 (a colleague of mine found one at
Staples for $10).
