Just curious, is it about different tools / workflow / the new thing to learn (and those are valid reasons!) or are there some technical issues with for example Winboat?
Honestly I think they really just don't want to change and they're trying to look for ways out because they know that "I don't want to!" isn't going to fly with me if I'm expected to be tech support.
The feeling of being able to work away from my desk and dont care about battery, is so goooooooood.
And I have to admit. Even if I dont like macos, my macbook with m1 and 16gb ram is probably the fastest laptop I ever own.
As I said in a sibling comment, I think they really just don't want to change and they are looking for excuses; I suspect even if I could prove that there's absolute feature parity between the two versions they'd just find another reason.
