Switching from Office to OpenOffice.org
This article goes into quite a bit of detail on how to switch from using Microsoft Office to OpenOffice.org. My only criticism is that it doesn’t address in detail the incompatibilities between the Office and the OOo file formats, or the problems that occur on both import and export. That might change, now that Microsoft has released the specs to the Office binary formats. But that change will take a while to happen.
