...but anyway, is it not in the best interest of 4.1 that it would be released for Mac Mini PPC to? Is the main reason you need to pay ~600 euro for the mobo (or 1000+ euro for x-computer) alone just so that Amiga dealers can force to sell 4.1 together with the mobo?
What you describe is a so called "business model" - and it is different from the MorphOS team. I suppose they try to build a new base of hardware AND software combination with more than one system deliverer. In this context the HW company makes some money, the software company makes some money, the dealers make some money - especially if they build systems for customers (like my sam440ep was pre-assembled by my dealer).
Of course the software part in this model could make more money if they port the OS to Macintoshs. But up to now Hyperion still exists and ACube still exists and AmigaKit and Vesalia as well - so it seems to work.
