If I understand it correctly, AROS will run a modified Aniga OS on a PC, and essentially turn the PC into an "Amiga"?
Not quite. AROS is a reimplementation which is not binary compatible.
Can I install AROS on one of my old PC's and turn it into a Miggy?
Depends on your definition of "Miggy". AROS doesn't run amiga binaries, except thru UAE.
MorphOS on the other hand runs OS friendly amiga applications directly.
