Most folks who use Dropbox simply use it to sync basic files they'd like to have accessible on all of their mobile devices. I personally find it to be a handy way of making all of my writing accessible on all of my computers. It is much easier to let Dropbox sync the drafts of this guide to my computers than to constantly send myself emails.

Syncing documents, however, is just the tip of the iceberg. Dropbox isn't picky about what it syncs. Stick a file in Dropbox and zam! - it's instantly sent to your other devices. This includes files like bookmarks, calendar databases and email databases.

In effect, you can use Dropbox to sync client software that relies on a local file to store information. Any software that has the capability to export or import the information used by the software can take advantage of Dropbox. This includes browsers like Firefox and Internet Explorer, calendar applications, financial applications and much more. Taking advantage of this functionality can make it much easier to keep software installed on different computers in sync. Just change your software's settings so that such information is stored in the Dropbox and you're good to go.
