Amiga vs. the World
I am still a card carrying Amiga follower after that I was disillusioned, the most I have achieved since is an anti-Apple theology.
Back in the day, Amiga vs the Apple Mac v. Atari ST v. PC v. TRS-80.
Back when Amiga had 4096 colours, PC had 4 colors (CGA), Mac was B&W, Atari ST was a wannabe and the TRS-80 was the backward cousin.
Oh the fun we had demeaning each other, none of these interwebs, you had to argue face to face, when someone walked into enemy territory and started bad mouthing.
