The Register posted an article ("Zombie PCs spew out 80% of spam") that says Windows-based system are responsible for about 80% of all junk email.

"Four-fifths of spam now emanates from computers contaminated with Trojan horse infections, according to a study by network management firm Sandvine out this week. Trojans and worms with backdoor components such as Migmaf and SoBig have turned infected Windows PCs into drones in vast networks of compromised zombie PCs."

This makes me wonder how long Microsoft will set the public's expectations for software. As things are today, a good number of people think it's completely normal for a personal computer to regularly freak out, crash, lose files, etc., yet they fail to realize that there are alternatives to Windows (and no, I'm not trying to be a Mac zealot... any Linux would be better than Windows, as would OS X; BeOS would be cool). As somebody who writes software for a living, I look forward to the day when Microsoft is no longer the reference point in people's minds.
