Did I Miss a Memo? I Thought the Browser Wars Were Over?

According to Mary Jo Foley, the Safari Web Browser may be coming soon to Windows' users. I can't even begin to understand if this bothers me more from a CSS designer perspective (anyone who's tried making a complex CSS design for Firefox, IE AND Safari knows what I mean), or more from a Business perspective.

The browser wars are over. We've all moved along (or so I thought). Since RSS our focus has shifted from the medium (the site) onto the content (through our feed readers).

Why would anyone bother to compete with Mozilla/IE on any platform? Seriously, Apple - Mozilla and Microsoft have got it covered.
