For a change I did a Debian install of 4.0 on my HD where you can see why a DVD is now needed. Never ending, cascading, menus. That is my point. I found myself having to go from Gnome, to KDE to Knoppix, etc. to eventually get it all going. Did I miss something? I didn't have a problem following it all but I imagine it would be a daunting task for someone new to Knoppix.
