" With the exception of exploitation of unpatched vulnerabilities, I've never seen malware lead to a system compromise on a properly-secured Win XP machine"
Sorry but how many (l)users know how to this? How many home owners even know this is possible. I would much rather see a Windows Vista with UAC turned on or Windows 7 in one of their hands than the typical XP box. You can teach people not to click Okay or Yes and then call and ask or just go on with out allowing the security holes. Yes it is hard to do and no you sometimes have to make it hurt to get their attention but like James says charge them more each time they bring in a corrupted system and they pain will cause them to start using their heads.
