This is good news. Open Office, the main challenger to Microsoft Office, has now passed the 100 million user mark. Corporations and governments right and left, mainly in Europe, are adopting OO and the ODF document format, and booting Microsoft out of the game. And the latest bit of news is that IBM has decided to join the Open Office Organization, contribute code it has written, improve interoperability with Lotus Notes, and to push Open Office as a product.
As you probably know, IBM adopted Linux as the standard OS throughout the company some time ago, so this is a logical next step.
