I had exactly the same thought. And this is not meant as an attack or anything on OP. But after reading OP's comment, the question in my mind was indeed "ok, but how exactly does it make you more productive?"
Large 4k virtual screen is what makes me more productive vs my laptop screen.
I'll often have charts, etc. on a massive Safari "window" next to the virtual Mac screen, which is useful too.
Plus, side benefit for me who doesn't always have great posture, it helps me avoid being hunched over my laptop, I can place the screen nice and high in front of me.
