Switching To Scrivener 1 Day In...Am I Crazy?

Yesterday R.J. introduced me to Srivener, a tool for writing documents.   Anybody else out there using it? 

I watched the video and was interested enough to download a free 30 day trial.  Ten minutes into playing with it I was hooked.  So I've decided to use it the next 29 days not only for NaNoWriMo, but to add the 4th draft of book 1 of The Courier.  Am I crazy?

Oh, and they're actually selling a half price copy to anyone who wins NaNoWriMo at the end of the month.  Another incentive to finish.
