HappyMartin, the tutorial with Scrivener is a wonderful thing. I don't think I've ever seen its equal. It not only shows you the product features by actually using the product, but by doing that it shows you how the product was intended to be used - an important distinction that can make a huge difference to faster productive use. As a software developer of many years experience I feel that I've learned some important lessons just by sitting through that tutorial. (Of course, it does help that it has a fairly narrow scope, we don't all get that luxury.
) I didn't end up choosing to use Scrivener, but that tutorial embedded in the product still impresses me.
