Fedora Core 6 won't cost me a dime.
Fedora Core 6 (as with every other Linux distro) is a great OS for someone who has the skills, time, and inclination to play sysadmin. For those of us who do not have the skills, the time, or the inclination to do so, Linux is still a very poor choice, and we're stuck, for better or worse, with either OS X or Windows.
