And in that same year you could get a sub-$600 machine that could do more than that C64 or Mac: the Atari 520ST! :)
of course the Amiga could do more than all 3 machines, but it cost even more than the ST (but nowhere near the cost of a Mac.)

Until in 1987 they made the Amiga 500 unit to compete with the 520ST, going back to the C64 the case is the keyboard design.
One thing about the Atari ST is that it was considered the real successor to the Commodore 64 because Jack Tremiel was behind it. Nicknamed the Jackintosh with the Magic Sack software it could run Mac software with a Mac ROM chip on a dongle.
It was the Commodore 64C that came bundled with GEOS.
They had a Commodore 128 version and a Commodore 16/Plus4 version of GEOS as well.
They also ported it to the Apple II series.
