The Web-based version of Office is, to put it mildly, underwhelming. It does a very nice job of accurately keeping formatting in documents created on the client version. But it's so underpowered as to be almost useless except for the most basic of tasks. I've yet to come across anyone who uses it, and with good reason. In some instances you can't apply themes or backgrounds, or even create new documents. Whenever I need to turn to a Web-based document creator or editor, I always turn to Google Docs instead, even though I use Office as my main office suite. A version that competes -- or better yet, outcompetes -- with Google Docs would be very welcome.
