 from what i can gather, capacitive touchpanels don't have "pressure
sensitivity" - it's too complex for the DSPs to handle: they're barely
keeping up with being able to calculate the picofarad-level charge
drops and distinguish this from stray capacitance from things like AC
current, charging, nearby objects and so on, as it is.

 i could be (and often am) completely wrong about that, though :)

 i don't see why not.  it's an absolute inputdev with crude but
reasonable accuracy (after plenty of de-bounce processing).
