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.
Love and use them for Photo, Publisher, and Designer, but there's no alternative for Lightroom. And honestly, I like Lightroom. It truly is the best at what it does. Simple, easy to use, great features, thoughtful design.
