I expect I would have gone the PC route... I was being pulled three ways...
Acorn Archimedies at school... One friend with an ST and one with a PC... I prefered the games on the PC... The Mac sucked at everything back in 1989, and I would have been embarassed at using a one button mouse.
Then I saw an Amiga500... I was totally blown away... had to have an Amiga after that.
