Exactly. That's all I want. Hopefully a higher price means they can live on that alone.
And they have fonts which not everyone in the world is using. Maybe Scrivener does too; haven't checked.
But maybe this will start a flame war: Guy Kawasaki recommends Adobe InDesign. To hell with monthly fees, so no.
