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.
I did (but also for games). That wasn't the problem. The problem was computers built on closed architecture didn't have a future even if company didn't went to shit like Commodore did.
Like Apple/Mac?
