PCMag.com has the column saying OpenOffice could present the biggest challenge to Microsoft Office to date. "The problem for Microsoft is that open-source code problems get fixed rather quickly by hordes of eager programmers. This has been the case with Linux servers, and OpenOffice should be no different. Microsoft has only a few alternatives.
First, it can make Office more powerful and interesting. The problem is that the suite's feature set is full, and now others are copying it. Little can be added.
Another choice is to lock down Office by integrating it tightly with the OS so that nothing else runs. But that would risk Microsoft's OS cash cow. People might actually dump Windows if the company did that."
