Who cares? What does it matter which part of the chain is responsible? The only thing that matters is the result. And the result is that you cannot use a "modern" touch screen for anything requiring precision.
multi touch is mostly needed for games and other kids stuff. zooming in and out is more comfy with volume buttons, or any other single-touch gestures. having a physical keyboard means that you can play any games without even touching the screen. sooo FxTec Pro1 might even come with resistive and presice touch screen, supporting _any_ object as stylus. buuuuuut everyone would squeal like pigs about it being soooo old and non-modern regardless it's properties so it's impossible.
