I downloaded the trial version of Scrivener for Windows, and I am very pleased with what I have seen so far. I have been able to break down my writing into more manageable pieces, and this is a wonderful thing for me. 
I am happy to see that speech recognition is being integrated into this program. I have used Dragon Naturally Speaking in the past, but have had to discontinue using it because right now the price is cost prohibitive to me. Microsoft Windows has a speech recognition program that compares well to Dragon Naturally Speaking. I would like to see the windows speech recognition program also be integrated for use in Scrivener.
