I'm still relatively new to this and I can't find what I'm looking for.

* I have a 25Gig Partition set aside for Knoppix so space is not an issue.

What are the advantages of installing knoppix 3.7 and downloading lots of packages over:

Installing Knoppix 3.4 DVD and running 'apt-get update' and 'apt-get upgrade'... wouldn't it upgrade all packages??

Also my laptop is a P4 so can I just download a new i686 kernel and everything goes faster I never understood that. (also what is the difficulty level of that on 1 to 10)
