Quote:some direct capabilities for the calculator to directly interact with things

Well, the calculator interacts with anything which can be made to speak a compatible USB CDC protocol and can be bent into using the appropriate USB VID:PID, seemingly.
And USB HID keyboard on the 83PCE/84+CE, we can all hope the Nspire grows such functionality out of the box.

But for interacting with real-world equipments which produce or consume data and control, all of our calculator models with very poor I/O capabilities (the 83PCE/84+CE, Prime only have an USB port; the Nspire has an additional dock connector with semi-undocumented pin assignment and an uncommon physical pitch, so it has basically nothing) need something that provides digital inputs and outputs, analog inputs, why not PWM output, and other kinds of useful I/O.
