DistroWatch Weekly reviews the pre-release LiveDVD of Knoppix 5.0. After reading this review, it sounds like Knoppix 5.0 will be great.
If you are still using KNOPPIX 4.0.x, then prepare yourself for a major update when version 5.0 finally hits the public mirrors in the next few weeks. It’s good; in fact, it’s probably the best KNOPPIX release to-date.
