So you like Ubuntu. Should I add it? What does it do I wonder?
Actually, I prefer Debian distros, but Ubuntu seems to be a bit more cutting-edge in some areas without treading too heavily into the Unstable/Testing (/cutting-edge) areas.
Still getting this main machine ready to revert back to a previous well-established stable distro, but have been busy evaluating some of the newer ones to see if they have more advantages. No luck so far...
They aren't Apple Mac OS X utilities. They're versions of Linux, a Knox off of the underlying UNIX operating system of OS X, but really a completely different operating system. None of what you use on OS X will run on them.
