I'm a big fan of Google Apps. We use them at my firm for gmail (using our farrellkramer.com domain), shared calendars, chat, and Google Docs, which is an office suite.

Now, here's somone who's really interested in the application. The author of this post is writing a book about Google Apps ... using Google Docs as his word processor. He discusses it in great detail:

Pros and cons to using, say, MS Word

• Working from anywhere: In theory, as the book is stored on the Google server farm and not your home computer, you can access and edit it from anywhere, like an internet cafe, or your friend's computer, or a public cafe with wifi. In practice, when writing a book you need to concentrate quite a bit. Some authors may be able to concentrate better when hooked up to their laptop in a public cafe, while others need to go have a non-changing, quiet place – like their home desk, room doors closed. If that's the case, then the "work from anywhere" bonus of online applications is somewhat lost. Nevertheless, the fact that Google Docs allows me to collaborate on the same document with my editor, who sits across the ocean, is a great benefit.

Beyond the pros and cons, the author discusses his workflow -- both in terms of writing and collaboration -- with the very clever use of features such as linking one doc to another and using color coding to specify the draft status of each chapter.

Basically, this is a very cool look at the real power of Google Apps: You can write together with someone else in real time, across geographic boundaries. Even something as complex as an entire book!
