Here we go to the offtopic forum...
I just want to mention that despite being a complete Zealot (albeit one with a lot of cross-platform experience), I was really just trying to point out the advantages of using something other than Windows if you deal with incoming mail from a website--thanks to all these ridiculous internet-cache-scaning virii, I'm getting 5-10 virus infected messages on a good day (there have been days with over 100), and many of them look like the sort of legit attachments I get frequently.
I shudder to think of the potential of nasty infections if I ever got lax with security. As it is, if you aren't using Windows (this all of course applies to other *NIX variants, BeOS, and anything else), it's nice to scan through virii-spawned junk with confidence.
If only there were a relatively easy systematic way to proactively deal with Klez junk on the Dreamhost end of things, but that's probably more trouble than it's worth for Dreamhost. It does get annoying with auto-responders, though, since the people targeted by them aren't the ones who sent the garbage. Grr.
(And just in case there was any risk of the flames dying down, I can't say I've had a crash in MacOS X in 8 months (nor any other problems that come to mind), so I'm happy enough being single-platform, as it gets the job done. That, and the BSD subsystem is fun, particularly for things like ssh-ing into my Dreamhost account.)
