        The point is, I can't see a real difference between a ROM chip
        and a decoder + gates. Electronically they're much the same
        thing. Physically, to change the program, I have to use a
        soldering iron. It is _not_ clear to me why one is called firmware
        and the other called hardware.

How about .. Hardware is the physical part(s) of a design that can be
seen, touched, crushed, thrown, weighed etc. Firmware is the idea
statically implemented in that hardware.
