It's not quite my daily driver yet, but I have a 65C02 based "dumb phone". The modem is a 4G LTE modem, but the electronics and interface are managed by a 65C02. It's currently being emulated on an ARM SoC, using a hand written 65C02 emulator, but at some point in the future, I'll port the firmware to an actual 65C02. The whole thing started as a joke. I ported WozMon to it, so that when folks ask me what sort of phone I have, I can call it an "Apple clone". But, I can use it to answer calls, send and receive text messages, and do very basic cardinal direction and distance based GPS navigation.
