The PC version runs blindingly fast under Windoze on a modern PC (I tested it briefly at work some years ago and it was SO FAST).
So.? There is an Amiga emulator for Windoze, the Mac (not sure up to what Mac OS, and Linux. To illustrate just how GOOD the Amiga was, there is today an add on EBay for a Toaster system starting at $1400 - for an almost 20 year old computer! And there is at least one Amiga club in existence. There are still professional videographers using Amigas, typically with a Video Toaster. Perhaps a few other people will recall the Amiga computer, manufactured from 1985~1994 and offering full 32-bit realtime multithreaded multitasking and awesome hi-res audio/video and Kinect style interactivity.
