I'm using the newest version of Knoppix 3.4 and i noticed it still has Adobe Acrobat Reader 4.0 in it. Some of my PDF files dont seem to load properly and on my Linux machine I run most of the time at home (slackware) I have Adobe Acrobat Reader 5.08 installed.
Since most of the software is cutting edge why not put the newest version of Acrobat Reader on!

Also it would be nice to have the default setting for KDE to show window content while moving and resizing windows as it looks much nicer.

One more thing, Firefox would be GREAT for a standalone browser to have on there, but thats not that important.
