If you put just one open-source software package to work in your small or medium-sized business, I can tell you exactly where to begin. And as much as I like Linux, I actually have something else in mind for you.

Linux is very likely to save your company both money and time in the long run, but it also requires a significant up-front effort to get it working and to migrate your Windows-based systems. Many smaller companies, however, can get up and running on OpenOffice.org (or its commercial cousin StarOffice) in a matter of days, if not hours.
