That "just a mobile phone" is a computer in small form factor and possibly more powerful than computers two decades ago. Especially on Android devices where you can run chrooted a full GNU/Linux environment, the only difficulty (but not a barrier) smartphones have for being used productively are the small display screens and the lack of keyboard.

Yeah I don't think anyone is under the impression that any smart phone is not powerful enough to do this, but have you actually tried development on a phone? Even with a keyboard this is masochistic.

But many seem to think that smartphone implies being limited to mobile apps to do work which fortunately on Android isn't the case. Tried to see if it's possible but no, I haven't used it to build something substantial. I didn't mind that much the small display as the lack of keyboard. A phone with slide out keyboard will probably be a fine choice for this usage.

Have you ever coded on a commodore 64 plugged into a CRT television via RF?

People adapt to what they have.
