There are also Java, etc., IDEs with which you can develop full Android apps. And have been for nearly a decade, at least.

Termux lets you run a sandboxed Linux system (can even include a desktop environment, rendered via VNC). You can run C compilers and whatever else.

Sure, I'll accept that. But the point isn't that the devices _are_ something specific, rather, the point was that the device _isn't_ considered a phone by the manufacturers. "Phone" is one function of the device, but no even its major selling point.
