It is all over the news, but it’s not that new. Microsoft has just legitimized openoffice.org as an opponent office suite… Actually, Microsoft has been answering about Office vs. OpenOffice.org for quite a long time now.
Googling for “office vs. openoffice site:microsoft.com” (without the quotes) just returned “About 2,460 results” in the microsoft.com domain and 5 of these date back to 2001.
This reminds me of the time Microsoft compared Linux with Windows, legitimizing it as an opponent OS and marking the start of another era. Googling “windows vs linux site:microsoft.com” (again, without the quotes) for fun returned “About 13,500 results” in the microsoft.com domain and 6 of them date back to 2000 or earlier.
Is it history repeating itself? Hopefully, yes. Only the name to look after in the future will be libreoffice from http://www.documentfoundation.org/, or whatever they finally call it.
