The Google word processor

I am using Google's online word processor. It does everything a word processor should do but automatically stores all my documents online. It is a snap to back-up by saving onto my desktop (downloading from the web is a lot faster and simpler than uploading to it, in my experience). If I were a collaborative type of chap, the ability to share documents and the automatic saving of previous versions would be most useful. Google desktop is now working well, virtually creating a new architecture for using my computer. This is not an original observation but Google seems to be sneak-thiefing Microsoft's precious PC computer operating system dominance and squirreling away a new operating system online.
