In the US Amiga was a niche player. Video production nerds went crazy for it and some people got them for games, but PCs were so clearly the way forward that you had to be something of an iconoclast to go for the Amiga. Macs were another niche player, although some businesses went for Macs which gave them a bit more of a "you can justify this by saying you'll work from home sometimes" purchase. In the US it's harder to convince people to spend thousands on a machine that's only going to be used for games.
