A: (Steve Jobs) It's like we said on the iPad, if you see a stylus, they blew it. In multitasking, if you see a task manager... they blew it. Users shouldn't ever have to think about it.

The point was that using a stylus as intermediary when doing basic interaction with a touchscreen is indirect/awkward and unnatural (the mouse is too, frankly), not that nobody should ever use a stylus for drawing.

Styluses clearly have a big precision (and visibility) advantage vs. tracking a whole fingertip touching/sliding around the screen (i.e. if we compare inherent human capabilities, not specific hardware), but relying on a stylus is also much more prescriptive about acceptable hand movements, and all of the stylus-first mobile devices pretty much suck compared to finger-based multitouch, in practice.
