> So, within 4 years we went from the "Personal Computer" becoming a real actual thing with the PC, to having basically the same desktop metaphor we still use today, with the Amiga. That's incredible development speed.

Except in 1984 we had the Macintosh, and a year before that we had the Apple Lisa. So only 2 years. Even faster.

(Before you start comparing with MacOS v1 and Windows v1, yes, true, but Windows 1 has clunky UI and neither MacOS nor Windows could execute more than program at a time. Only Amiga had that.)

I picked my goal posts arbitrarily, but an Amiga could basically run all software we have today, if the CPU was faster. Stream music + download something + editing a text, for instance. The Mac OS could only have done this a little bit later.

But sure, yes, the UI of the Mac was incredible, only 2 years after IBM PC.

The Amiga had proper preemptive multitasking (what I would consider a key part of today's "desktop metaphor"), long before the Mac.

The Apple Lisa had preemptive multitasking years before the Amiga.

So did many systems. About 3 people used them.
