Looking at the price of this and other calculators, I wonder if there's a market for "dumb calculators" analogous to dumb terminals: a device with the calculator form factor, keyboard, and display, but where the actual computation happens on a paired computer/phone or a cloud endpoint over WiFi/Bluetooth.

The cost of these devices isn't the computation, and if anything more connectivity would probably make these more expensive and harder to use (many "smart" devices in classrooms have networking issues and if even one of them can't connect, it hurts the ability to run a lesson). I think standalone computation abilities are pretty important, and connectivity can be a downside for preventing cheating in standardized exams etc.
