Scrivener users?

Are there any Scrivener users aboard authors.com?  With the Windows release of the product, I was pleased to finally get a chance to try it out while revising short stories for my L.A. Limo Tales collection. Must say that I've barely scratched the surface of its capabilities but I'm very pleased with its ability to produce clean e-book files in all the major formats.  It looks to be an excellent writer's tool and it's already providing benefits as I revise my crime novel before e-publishing. 

Anyone else here use Scrivener?
