Because some of us prefer Windows to Linux on the desktop.
My point was that I don't see the sense in the strategy laid out by grandparent, because I don't see a compelling reason to run Windows on servers (I say this as a former Windows sysadmin (as recently as this year, not 2005)).
corysama, I agree. Windows was really lacking in any type of native unix connectivity. No native ssh, sftp support is a big one. You can get free third party programs for that, but nothing beats opening a terminal and having all of it, especially if that's what you are accustomed to.
I really love the new shell in Windows. I'm so glad they broke away from their old mindset.
