Yes !!! Soon Iridient Digital also for Windows / Linux (Public Beta in March/April)
It is considered by many the best RAW converter for your X-Trans files: Iridient Digital! The problem so far? There is just a MAC version.
However, this will change soon. According to a comment to this stevehuff article, Brian will launch a Windows/Linux Beta version in March/April:
” I’ve made major progress on the Windows (and Linux) ports of much of my RAW processing pipeline in the past couple months. I hoped to have a public beta in Jan-Feb, I’m now aiming for March-April. Initial product(s) on Windows won’t be the full Iridient Developer application, but the most critical processing elements will be there. For those that use a primarily Lightroom based workflow the new product(s) should be more convenient and have a much lower learning curve than a more full featured RAW processor like Iridient Developer anyway.”
