i think i was a good video but videos like this had a more powerfull effect on me at least: http://audio-video.gnu.org/video/rms-education-es-high-sub.en.ogv
also why is there non-free software in this video??? pause at 2:18 you will see a firefox logo! but anyway a good video!but if anyone from the fsf is reading this please replace the firefox logo with icecat of another libre browser
