I have had 3 amigas since 1993,the amiga600,the amigacd32 and the amiga1200,and i have to agree on one thing,the amiga always had a superior sound quality than the Sega machines,but when it comes to arcade gameplay it sucked a bit when compared to the some of Sega games.
But the Sega machins were concentrated in games only,while the amiga is good for programming,games,demo watching,music..etc,etc
:-D
