We're talking about a home user here. Usually, the typical home user
has no LAN. If she/he has one, we both agree, that she/he should use
an appliance.
The Windows-Firewall is properly configured in Windows XP SP2 as default.

Good point. Of course, no user should work as administrator. It's
catastrophic, that Microsoft determines so many users to work as
administrator because of the disastrous misconfiguration, which is
default for many Windows products.

It works without problems. Just test it out.

And why not using the Windows-Firewall, if one has Windows XP?
It's properly configured by default.
If malware is already running on a box, then it's too late. Also an
appliance will not secure this box any more.

I'm claiming that for single hosts only. Beside that, you're wrong. I have
23 years of experience now with computers, 21 years of them with users.
And many, many incidents of compromized machines. Usually, before I come
the very first time ;-)
