I too had been using MS Word for years to write the various articles and reviews that I do. But for my last article (http://www.smallcloudbuilder.com/apps/articles/410-crossing-...) I switched over to Google Docs. For my use, it worked fine. The feature I missed most was the live word count that like the author, I had come to depend on when writing articles of a designated length. Google, are you listening? :-)
You can extend the functionality of google apps using apps script. I thought it was already in use and there were libraries of extensions, but I don't see any. But I'm guessing they will be coming soon..
