Meg, have you watched the
tutorial videos?
I tried the 30 day trial, and bought it after about two weeks. It just does a lot of things the way I want to do them, and keeps the clutter of most word processors out of the way so I'm not tempted to play with the fonts for 20 minutes.
I like to write in blocks -- an action scene here, a slower dialogue scene there, something way far-out further in the work that I'm going to need to start foreshadowing, or something further back in the manuscript that I want to flesh out.
For some of the stuff I'm working on, I have a lot of pictures and diagrams that I keep referring to: Scrivener lets me drop them all in one place so I don't have to keep hunting for them all over my HD, or keep switching to different applications to check my notes.
And not knowing how long the writing projects I'm working on will be, I like the flexibility that Scrivener offers for keeping the monsters organized-and-self-contained.
I'd be interested to see from people who
don't like the program -- what
didn't work?
