Jay,
take a look at the news column (http://www.thecodemill.biz/services/oacs/) or the changelog (http://www.thecodemill.biz/services/oacs/changelog/index?revision_id=10054) of Emacs OACS. You'll notice that Emacs OACS does a lot more than what is mentioned in the articles. As this is still a beta release, documenation is behind the development curve.
If you are an Emacs user (and even if you are not) I recommend giving Emacs OACS a shot. Use the changelog to learn what Emacs OACS has to offer.
