This is awesome. I am running Knoppix 3.3, a GNU/Linux distribution installed onto a CD. There is no installation, no dual booting, no mess. Simply boot from the CD and it loads KDE with most of the applications one would need. I was skeptical at first, but I would recommend Knoppix to anybody who wants to try something outside of their Windows world. Even those who do not care to learn about Linux should get Knoppix as a backup in case they need to re-install their OS and need a temporary solution for Internet access and the like.
