A wise choice, Supermike. (I've got OpenOffice on my netbook and I love it).
Just a (hopefully) helpful hint though:
By default, OpenOffice saves files in its own formats, which are NOT compatible with Microsoft Office formats. (e.g. it save word processor files with the extension .ODF, rather than with .DOC). So if you simply click 'Save' and then email your file to someone using Microsoft Office, they won't be able to view it. The trick is to select 'Save As' and then choose a Microsoft format from the menu.
However that can get tedious. A far better solution is to change the default settings, so that files are AUTOMATICALLY saved using Microsoft formats (simply by clicking on 'Save'). The instructions you'll need are here:
