I found this article on Slashdot. It is a well written commentary on the state of Unix/Linux, although I'm anot sure how many OSS advocates would agree with the conclusions.
My evil twin particularly liked the following passage:

I installed Linux on one of my systems the other day, so I could use it as a teaching vehicle for my class on system log analysis. But first I had to Email a bunch of my friends and ask them, "what version of Linux should I use? Red Hat? Debian? Gentoo? Mandrake? Slackware? Do you think I could get away with OpenBSD or FreeBSD?" The responses I got indicated that none of my friends use the same thing but that I could be sure that if I used Flavor X some adherent of Flavor Y was going to bust my chops about it, and that someone was sure to show up with flavor Z and have trouble making things work.

Do you hear the sound of distant laughter coming from Redmond? I do.

The early days of the Linux movement was heralded with grand pronouncements of war to the death with Microsoft - war from the desktop to the data center, and a free, compatible high performance alternative to Windows. What I see now is that the open source movement is more like a 14-year-old punk standing in the street telling Mike Tyson that he had an a**-whipping coming. Not the Mike Tyson we see today, either, but the Mike Tyson who could deliver a line-straight punch and knock a hole through the side of a steel I-beam.

(The colors are the original author's). 
Quite an interesting read.  I'm sure the Slashdot crowd will have a field day with this one :)
