This is how I use Ubuntu… if you mind?

• Remove Mono

  sudo apt-get purge libmono* libgdiplus cli-common libglitz-glx1 libglitz1

  source

• Replacements: F-spot → gThumb, Tomboy → gNote, Empathy −> Pidgin

  sudo apt-get install gthumb gnote pidgin

• Nothing to do with Mono but I don't use Gwibber or Empathy either

  sudo apt-get purge gwibber empathy

• Medibuntu - because the notion of property is not the same all over the world. Thank god.
• Ubuntuzilla - for the latest stable mozilla builds
• deb.opera.com - because I do webdesign
• http://archive.canonical.com/ lucid partner - needed for Sun-java6, a requirement of Processing

  sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
  sudo apt-get update   
  sudo apt-get install sun-java6-jre sun-java6-plugin
  sudo update-alternatives --config java

• http://lgp203.free.fr/ubuntu/ (Don't remember why I had this one in my previous Ubuntu install. It's just here for decoration. Will see what to do with it.)
