If you don't want to spend 300 bucks for the new Microsoft Office Suite, this
Free Office Suite might interest you. It's a shade over 100 Mb's, so you'll probably need a broadband internet connection to download it. After you download it to your
Desktop or
My Documents, go to that folder, find the Open Office file and just click it to open and it installs itself. Pretty cool.
