You can also create new text documents and diagrams using GDoc Binder's built-in word processing and diagramming apps. They're not as full-featured as their Microsoft Office counterparts, but they stack up pretty well against the Google competition.
To share binders from within the application, you can either distribute them via e-mail or use Dropbox. If you have Dropbox installed on your computer, GDoc Binder offers it as an alternative location for the My Binders folder where binder files are stored by default.
I did run into a couple of usability issues. Dropbox setup was not clearly explained in the documentation, but more annoyingly, you cannot create cover art (or even cover text) for your binders from within the application. If you want more than a plain solid colored cover, you must create it in any of GDoc Binder's supported file formats and then drag and drop it onto the binder. Once you've done that, however, you can edit it from within the app, which makes having to create it outside the app all the stranger.
Of course, you can save money by using Google Docs or some other free Web-based service for document sharing and collaboration. But GDoc Binder's pleasing appearance, familiar loose-leaf notebook metaphor, and great format support might make it worth the relatively inexpensive cost for some team projects.
