"the broken" is a little misguided. Microsoft software by itself might be fairly stable, but as soon as you add any third party software to windows, it starts slowly destroying things.
I use openoffice, the gimp and thunderbird, and they are by far on par or better than regular pay for proprietary software.
I have 5 Linux boxes that never need rebooting, a dual Xeon workstation which renders my gimp projects fast and reliable, 2 Linux servers, and two IBM Thinkpads with FC6. Oh, and my router runs FreeBSD. Another very good Unix OS.
Modern Linux distros are easier to install than windows, are reliable, powerfull, and run on anything from iPods to toasters. Did I also mention "virus free".
Whatever people's excuses are for not embracing free legal stable programs are, I don't know. Most are ignorant or just don't care.
What about the crappy linux desktop? Your not talking about a nice xgl rendered desktop are you? http://images.google.com/imgres?imgurl=http://static.flickr.com/82/207006905_3997271b2d_m.jpg&imgrefurl=http://swik.net/Compiz/Compiz%2BImages&h=180&w=240&sz=16&hl=en&start=29&tbnid=_hI5mFffLcS-kM:&tbnh=83&tbnw=110&prev=/images%3Fq%3Dxgl%2Bfedora%26start%3D18%26ndsp%3D18%26svnum%3D10%26hl%3Den%26lr%3D%26sa%3DN
You must be a XP user. The ignorant in denial.
