Apple were, I am assuming, the primary consumer of PPC processors.
Actually Apple used only a small fraction of PPC processors manufactured. Most PPC processors are still used in cars, trains and all sort of embedded systems (as can be guessed, amount of them can easily exceed not only amount of PPC based computers, but computers in general)
but then again, when talking about fast PowerPPC's (G4 and faster), then Apples share of them might have been significant. This might mean that they will focus more on processors aimed at embedded usage (less MHz, less power usage)
My question: Is Amiga inc. going to use the "buy back" option to buy OS4 back from hyperion once it's completed? If yes, have you planned any further in-house development?
