In my part of the woods all those consoles were frowned upon, back in the days when we had 386s, 486s and Pentiums. Yes, PS1 could display some interesting games, but you couldn't do anything creative on it.

As to what killed Amiga - I think it's in the article - the lagging behind the x86 performance, especially when 386DX-40 came about, and please allow me to propose one additional, if not the primary, factor - that our fathers suddenly began to require Word and Excel to do their work at home.
