Not a problem. I’m normally on Linux as well, and quite happy with Darktable.
I merely started my Windows box yesterday in order to have a look at Capture One and Lightroom and see what that’s all about. (And whenever I have to develop on Windows, I don’t like it. It’s nice enough for video games and such, but software development is a nightmare.)
Apart from the performance, though, there’s not much these programs offer over Darktable, I find. Lightroom in particular seems to lack a surprising number of features I’m accustomed to. Capture One has a very slick UI. But I really can’t tell them apart in their output.
I do a comparison like this every year or so. I usually come very close to wanting to buy Capture One initially. And then I see the price point and re-evaluate if a bit of smoothness is really worth that much money–and simultaneously realize that I’d have to switch to Windows if I truly wanted to use it. And then I play around for a while, and get to know the tools… and go back to Darktable, satisfied that it’s the best tool for my way of working. That’s how I deal with gear envy.
