Tyfon, your view is horribly misguided I fear. Some points to consider:

1) You don't have to pay for AV, spyware detectors, etc., as there are plenty of freeware alternatives out there. I run an AV, firewall, and four different spyware-detecting programs and haven't spent a dime. The only real issue is the ridiculous price of Windows.

2) A true expert can harden any OS by mastering it. A Windows expert can harden his OS as well as any Linux distro; conversely, a Linux user with no understanding of his OS can render it far weaker than Windows. In the end, security is defined by the man behind the machine, not the kind of OS he's running.

3) Gore as an MS advocate...Now that's just darn funny. Perhaps you should pay a little closer attention to what you're reading.
