The problem of the Amiga was basically that it was clock cycle linked. To really get things going with the platform you had to count cycles so neither the CPU not the chipset got hung up waiting for the other. This made the platform frozen from the moment it shipped. In contrast the PC was less rigid, and only really had the x86 ISA and the BIOS memory map in common (and even the latter is falling by the wayside in recent years). There was also the whole clone aspect. The Amiga stood and fell with its parent company, Commodore. Once Compaq and the others cloned the BIOS chip, IBM could belly up and the PC platform would barely blink.
