Darktable finally has official support for Windows. Not that I'm suddenly a fan of Windows or anything, but this does mean I can recommend it to a couple photography fags I happen to know. Rawtherapee is what I use anyway, and it's great, but a lot of people are already used to Lightroom's way of doing things.
