Welllll.... To amplify on that a little...Windows is a perfectly good desktop OS. Linux is a perfectly good server OS. Both are ill-suited (though not unusable) for doing what they are not best at (Windows as a server, Linux as a desktop). In fairness, Linux has come a long way on the desktop, but if you think it's ready for prime-time, just try installing the vaunted Ubuntu distro for a non-techie, confident they'll love it, and see how long it takes for the phone calls to come in. (Two hours, in my case.) In other words, it STILL makes a better server OS. To MS's credit, it's starting to realize this, too, I think, which is the reason (one of them) for the love fest with Novell. There really is room for two major operating systems - one that is reliable but clunky, for serving apps, and one that is buggy but slick, for serving desktop users. I'll leave you to figure out which is which. :)
