The other day, I was expounding the virtues of Debian GNU/Linux to an acquaintance. "Debain includes thousands of programs, and they're very nicely packaged. You just type in the name of a program, and Debian will download and install it for you."
"Oh," he said, "I used to use the Macintosh, but now I use Windows because I can get all my software for free. I just use Kazaa."
