I can definitely see the digitizer pen. That's mostly why I like the idea of being able to use an iPad Pro as a secondary display. Sketching something with a mouse or trackpad makes my barely legible chicken scratch that much worse. I usually end up doing it on paper and taking a picture.

But different folks, different strokes. I have a ChromeBook with a touch screen that I never use. But I have a friend who, if I hand over the ChromeBook to look at something, their natural reaction is to swipe the screen to scroll, which is something I almost never do.
