I think its true. New PCs are the result of what Amiga laid the ground work for...
and if you want to get really technical, Mac filled in for Amiga.
they seem to be one of the "in" computers to use for graphics work, video editing, and music. The only thing they failed to pick up on were all the kickass games.
oh and they are pricey, like Amiga's were, and still are!

Either way, wasn't amiga mostly striving for a powerful, multitasking, high end hardware concept that was usable in many fields ranging from home--->commercial stuff?
That's about where todays PC/Mac stuff landed!
