I wonder if I could ask a generic question at this point: how good is the
touch handling on (affordable) current and upcoming tablets,
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 :)
and would they
support something like http://risujin.org/cellwriter/ which is claimed to
recognise arbitrary Unicode characters but is designed for something like a
Wacom pad?
i don't see why not. it's an absolute inputdev with crude but
reasonable accuracy (after plenty of de-bounce processing).
