Interesting, I've written two novels and over a dozen radio drama series in Scrivener. Currently using it to finish first draft on a spec film script. It's pretty fantastic. Interested to hear why it didn't work for you - especially if the alternative is word.

Cross platform support (including iPad), saving direct to dropbox, full screen distraction free mode, easy sorting of chapters / scenes, rapid offline export to PDF (unlike say Celtex). Scrivener just blows everything else I've used to write out of the water.
