I’ve been playing with a lot of Linux distros over the summer. Once I’ve got an Mp3 player and media player that can play wmv and DVDs working and once flash video is configured, here is a list that follows of the stuff that needs to be installed. I love the distros like Linux Mint (based on Ubuntu) that has all of the above working out of the box.
Fspot or Picassa
Inkscape or scribus
Kino (best of a poor bunch on linux)
OpenArena – Quake
