Network Computing on Moving to OpenOffice.org from MSO
Network Computing publishes a detailed guide on when and how to migrate from MS Office to OpenOffice.org.
“From our perspective–both from speaking with organizations that have made the move and from having gone through sacred-cow change processes like this–it’s not so much a question of whether organizations should use free office-suite software, but rather how much to use and when. When you consider the cost of the incumbent Microsoft software (a couple of hundred dollars per license) and multiply that by hundreds or thousands of licenses, it becomes clear it’s not a matter of justifying the switch, but rather explaining the additional expense of keeping Microsoft Office around.”
