Fedora, basically the next generation in Red Hat Linux, is still kinda new compared to other distros, but is completely opensource. Anyone can work on it. If youre interested go to

http://fedora.redhat.com

for the 3 disc download, and a great community site is

Linux is awesome, and unless youre a hardcore gamer, you dont really need windows anymore. Just an idea.
