"While in it’s early stages, I contrast this with Microsoft’s Windows Pen/Ink support. With Windows a mouse is still available to use as a precision pointer, meaning most people will still choose this method by default. The presence of a mouse/trackpad enables the user to stay in their comofort level rather than embrace a new paradigm. The implication is the pen is likely only used for pen use cases and not in a position to become the new mouse. The lack of a traditional mouse pointer/trackpad is precisely the reason Apple has the potential to innovate and encourage software to be built around new precision input paradigms instead of old ones.The Pen(cil) is Mightier Than the Mouse | Tech.pinions
It will be very interesting to see how Apple continues to develop the gestures feature on Pencil and what developers do with it. I’d love to see Microsoft run with this idea and explore new Office experiences focusing on the pen as a new type of precision input that can go beyond just ink/drawing.
From a use case standpoint, when you need a precision input tool, there is not that much different in motion than taking your hand off the keyboard and using a trackpad then picking up the pencil. And, I’d argue that what can be enabled by pencil, gestures, and software, will take precision input to a level not possible with a trackpad/mouse."
