I think it makes perfect sense to port MorphOS to PPC mac. There's loads of old mac kit kicking around.
It would be rather nice if OS4.1 were ported too.
Amen to that! Now that we have AmigaOS4.1 released for the Pegasos, maybe one of the next targets will be one of the G4 PPC Mac models.
If Hyperion really wants to impress me and get me to seriously consider switching from MorphOS to AmigaOS4.x, all they have to do is port AOS4.x to a G4 PPC Mac model that is faster and better than the lowly MacMini. Not too much to ask for and without anything better than the SAMep and SAMflex boards available right now, why not port AmigaOS4.x to one or more of the old PPC Mac's?
