If you are an Ubuntu user and haven’t checked out Automatix2 yet, you NEED to.

Automatix is a graphical interface for automating the installation of the most commonly requested applications in Debian based linux operating systems.

After several installations, configuring everything the way I like (codecs, plugins, etc) I discovered Automatix.

My favorites:

The Network Manager that Automatix packages is terrific, it works the way a wireless manager should.  Searches for available networks, connects to open networks or a secure one you have established a connection to before.

The Check Gmail app is great, puts a gmail icon in you sys tray and notifies you of new email, you can also delete/mark as read from within the window.
