>>"It would be helpful if a kanotix user could list the pros and cons of using Kanotix and what is fundamentally different from Kanotix and Knoppix?"<<

Not much point, now that there has been a major split at Kanotix. Looks like Kanotix is going to be Ubuntu based from now on, but most of the people who held to the Kanotix vision have formed Sidux.com (based on Debian Sid), and are trying to release v1.0 before the end of the year. They already have fantastic documentation at Sidux.com, if you're interested. Kanotix was my favorite, but they stopped innovating. I have high hopes for Sidux.
