Smart man. On the other hand, go ahead and try experimenting with any apps that interest you. Just avoid upgrading OpenOffice.org. (Don't do a full apt-get upgrade.) If you mess up don't worry, there is a new image available. So, you were probably going to reinstall it any way. Correction: There is a new version of Easy Debian available in extras-devel (may be a bit rough still). A new image is about to be available.
