For those people who are curious about “Linux”, Cygwin/X is a great way to experience GNU without losing their current Windows setup, leaving Windows to boot another OS or sharing their RAM with a virtual machine. It’s also great at work for GNU users if they have the freedom to use Cygwin1 at work. It gives new users a chance to use the command line in ways that cmd.exe doesn’t support, and it gives a chance to explore a GNU filesystem. There are a whole lot of the same software packages available for Cygwin/X and Cygwin Ports: Emacs, GIMP,
Inkscape, Calligra (won’t open for me), etc, so these applications can be integrated with a libre software environment—opening and saving files to and from the home directory, updating them all at once with setup.exe or apt-cyg, and so forth.
