Windows benefits from a touchscreen more often on something like a diagram where you'll be panning around up/down/left/right, zooming, etc because the trackpad situation isn't very good.
I've never felt the need for a touchscreen when e.g. using Miro because I can scroll and all directions and zoom intuitively on the Mac's trackpad.
Eh. I don't think the Macbook's trackpad is that good. It's better sure, but it's still not as intuitive panning or rotating over the image directly on a touch screen. And it's still useless for drawing.
