Picture this: If Amiga were in the Mac/PC Commercial
PC = PC Guy in Suit
Mac = Mac Guy Cool.
Amiga = Tattoed Skat3r Guy
No, even if Apple would admit that other platforms than Mac and PC exist/ ever existed, the Amiga guy would most probably be a corpse lying down with a wheel mark over his belly. :-D
Oh, and PC and Mac guy would be in a car, one of them asking, "did we hit him, did we hit him?". That's about it...
