I use XP SP2, and have no firewall.  In fact, I've never used a firewall.  I rarely, if ever have any issues.  Once in a while I'll get some spyware, but Spybot does away with it easily enough.  On a rare occasion I'll get a virus.  Usually just because 99% of the software on my machine is pirated, and the cracks and keygens sometimes are infected.  I've never had a serious issue though.
