I'm happy to see that Scrivener is finally making its way to Windows.
Previously Mac-only, this wonderful writing tool is the main reason I own and use a Mac. It will be nice to have options in the future. And, even better, my Windows-using friends will now be able to benefit from Scrivener's capabilities.
You can read more about it here, or watch the video.
