After the live presentation of the Mini Port on the AmigaMeeting in Germany by Bigfoot, and he mentioned that he is waiting for his 15" G4 Powerbook to arrive to port it to that too i decided to replace my 12" Powerbook with a 15".
So i kinda did buy a Mac to run MOS on it.
But i think that the release will take some more time, i think 6-9 months from now on.
At least the Ethernet/Audio and PMU drivers are missing afaik.
