Yes, it is a question of will and want when maintaining a Windows version. For a long time, the developers my favourite Linux video editor, Kdenlive, said Windows was too broken to port it. But, eventually somebody turned up and now there is a Windows version.
Regarding OSs, it's all about what ever gets the job done.
But you could virtualise Windows on Linux and run your Windows software that way. ;-)
I agree 100% - what ever gets the job done.
I could run Linux and a virtual machine with windows (and I have in the past) but doing that legally would be more expensive than the other way around.
Ha ha, guess what, your wish is now granted! DarkTable is now available for Windows! =)
