A lot of words there. But the word ‘console’ is there exactly once. Games consoles killed the Amiga, just like they did all other home computers that were primarily used for games. I don’t know anyone that used the Amiga for anything other than games. PCs survived because they were genuinely used for business, not just games.
None of us replaced them with consoles.
While the use in business was of course important, that the PC survives is just as much down to the open platform and the clone market that prevented its future from being tied to a single company - in this case a wildly dysfunctional one.
