i refused or rather was not interested in p5 ppc solution since ever i remember. it was even partly the initial reason for me not to invest into the platform anymore since i regarded the technical solution clumsy, halfa$$ed while too complicated and therefore too expensive. it was clear for me that with decisions like this the end of the pole was near.
then i got the ppc board few years ago, wanting even to minimally to improve on what 060 amigas could still do for me. and was bitterly disappointed, getting os4 didnt help any further.
following development of 4.1classic since i admittedly like the w3d readeon support and compositing it got, alas it is not enough for me to invest into it and it doesnt look like it goes in any further (at least in a direction id regard any useful)
