One of the nice things about Knoppix is the many uses to which it lends itself. Some people use it as a troubleshooting or a rescue CD (there are tons of rescue type programs on the CD - most of which aren't listed in the K menu) while others, like myself, use it as an easy way to install Debian onto a desktop or laptop. Others use it as a means to have a familar linux desktop with them wherever they travel (with their settings saved onto some form of removeable media). In any event I'm glad it was useful to you.
