My follow up question would be: Would a capacitive touch screen with 0.5s latency have made this the killer feature? Or did the capacitive touch screen enable high speed input?
I'd argue the latter, but it could be a question of framing?

But you are right that the capacitive display itself makes the interaction faster because it's enough to touch while the resistive has to be pressed. So it's probably slower and feels like you have to put in more effort.
Sure, for many, iPhones are still preferred because of the low latency, so it matters, but I suspect the iPhone would've done just as well if the latency was bad. The competition was about finger vs keys/pencil, not latency.
