At least personally, my chief concern if I was considering "open source alternatives" for office software would be to ensure interoperability. I use office software for both personal and business purposes, and I need my documents to get across in perfect shape to their destination for the latter purpose. For better or worse, that is ensured not by whether source code is open or closed but rather by simply sticking to industry standards, also known as using what everyone else is using. That means Microsoft Office by far and Google Docs to a lesser extent, whether anyone likes it or not. I suppose I should put it out there I also like paying for and using Microsoft Office anyway. I get back much more than what I pay.
