It would be nice if the pen had a dual purpose upgrade. Pen / Stylus. Maybe have the eraser side of the pen be a button itself. This could offer two potential benefits.

First, lite touch to screen and it erases as normal. Hard press to screen, eraser size gets bigger. This would speed the eraser process.

Second, press with thumb like a normal pen action would turn the pen to stylus, press again and back to pen. This would eliminate the need to use your finger to navigate and use the pen to write. One tool for both, a click away for a more nature way.
