I agree with your sentiment - but at the same time I've been thinking a bit about this (not-mouse, not keyboard input - and text editing). I think that multi-touch screens might be a good-ish fit for something ACME-like (note: I'm not an ACME user). One-finger to select, two-to (do whatever it is that typically does), three for action etc. Two-finger hold+third-finger-tap. That kind of thing.
My main motivation is that I've developed RSS pretty early, and while I can function with a keyboard, using the mouse more than just a little bit, will quickly trigger a fall-back.
Add to that, the idea of reducing ten digits to a single (or three) buttons, doesn't strike me as optimal -- only easy (considering a serial interface, simple hardware).
That said, efficient, non-strain inducing touch interfaces pretty much dictate the same kind of restrictions that pen-"input" (drawing) does: a drafting table/slanted screen layout -- not vertical screen, horizontal keyboard.
And I do think that ACME has some valuable ideas that could help make multi-touch work for efficient text (and other) editing.
If it entails repetitive strain syndrome, I'll pass.
As I understand it it is oriented around three buttons -- I suggest that that might be achieved with multi-touch (I can see how it might be difficult to distinguish "hold-one press two", and "hold-one press three" -- but I don't think it is insurmountable to achieve a lot with proper multi-touch and some smarts).
