LibreOffice is a FREE comprehensive Office Suite - for Linux, Windows, even Apple (NeoOffice)! (OpenOffice is the Oracle/Apache version used by many businesses.)
Abiword is an elegantly simple Word Processor; and Gnumeric is a powerful and easy to use Spreadsheet from GNOME Office.
KOffice (part of KDE) is maturing as well.
There are Windows versions of LibreOffice, OpenOffice, and Abiword. There is even a project to bring KOffice (and the whole KDE Desktop!) to Windows (KDE on Windows).

Anti-Spam
Very intuitive "trainable" Junk Mail filters are now built into the Mozilla Thunderbird mail program!
