I have heard that there are PPC distro's of Linux for use on the Mac's, was just wondering if anyone had used one and what they might recommend. Was purley out of curisoity.. but you never know.
Check out the Ubuntu live cd. It's probably the fastest/easiest way to try Linux on a Mac, plus, you don't actually have to install anything. Some other distros with PPC versions are: Gentoo, Suse, Yellowdog, Debian, etc.
