Marty, this guy (sorry if i got the gender incorrect) is a Linux Newbie. Knoppix is a fine distro, and i use their live DVD, but it can be a bit difficult to install for a newbie. Sure you want to steer him or her in this direction?
AFAIK, Ubuntu/KUbuntu/XUbuntu (they're all the same distro, they just use different windowing environments) are much simpler to install.
