I think you will find it is because phase 5 had already made ppc acelerators for older 68k based amigas, and it was a easier to use ppc than an x86 chips, i think ppc has some sort of compatability with 68k and it also runs very cool meaning it would be better for imformation devices where there is not much room or airflow.x86 would need a lot of work and i reckon it would cost a lot more to get a board desighn. ? :-)
