I think you're missing the point... At the time the stylus was the device you used for everything, typing, navigation, and so on.
That was awkward and frankly just "bad." Humans don't want to poke at a device with a pen all day, it is unnatural, and also slow (particularly for typing!).
Many of the touchscreens were also terrible (thus why the stylus was seen as a good alternative).
A stylus for drawing is wonderful. But the iPhone/iPad was never a device designed for drawing or creative endeavors specifically.
