There is an interesting "History of the Amiga" article in Ars Technica [1], and the sense I got is that the Amiga didn't win out for non-technical reasons.

It was, hands down, the best hardware/software combo out there. If I remember the article correctly, the Amiga failed for other reasons. Bad marketing, bad Commodore management decisions, etc.
