I held off on Windows 10 for as long as I could until Adobe, and therefore my job, required it. Now this nonsense. I hope this isn't the start of them joining on the web DRM bandwagon.
I got in on the Kickstarter for the Abode (not a misspelling) software suite by Stuart Semple and am hoping that when they release that it at least beats Darktable. Also, Darktable is pretty great as a free alternative to Lightroom.
Edit: I named him because he created the Freetone color palette when Pantone upped their license fee on Adobe. He also made a few paints and sells them at reasonable prices as an accessible alternative to more expensive paints.
Also DigiKam for the photo management side of things (I usually find that DarkTable is best suited for retouching). Between these two I don't feel the need for anything Adobe. Granted, I'm just a hobbyist so I can't speak from a professional point of view.
