A project from Michael Robertson called ajaxWrite, is another web-based word processor. The nice thing is, you get a window to yourself, and that window (complete with tabs for your docs) is a pretty basic word processor. What's really impressive is the speed and stability of the app. That could be due to it only being compatible with Firefox, as having only one target allows you to focus on streamlining your performance. The essential feature is the ability to save your writing as a Word doc (the default), plain text, RTF, or PDF. Some limitations appear to be no inline saving, so if you lose power or your connection, you'd have to copy/paste your work to another program. With no signup, speed, stability, and good Save As formats, it appears to be a useful tool for when you're needing a web-based word processor without all the bells and whistles.
