As the Future Lawyer notes here Google has begun its assault on the Microsoft Office monopoly, although they are down playing the obvious head on competition. I don't think anyone is really fooled. Google's strategy is to erode Microsoft's MS Office monopoly power a little at a time. Their offering will quickly mature into a robust offering for small to medium size companies and startups. It will leverage the momentum building around Web 2.0 and might grow even faster if it makes it easy for developers to build add-ons and mashups. The "everything on the cloud" computing strategy is nascent but inevitable. That said, Microsoft sees the writing on the wall and will respond with a vengeance. Let the game begin!
