I stopped reading replies at page 3, I've read many interesting points but also many who have their heads in the clouds.
Provided the good will (and good faith) of CUSA, I think the most affordable way for everyone is to stick to x86.
I'm really sorry for AmigaOS and MorphOS, but sticking to PPC/esoteric hardware it's a neverending fight against obsolescence.
Come on, AOS is a complete rewrite as AROS is, so which should be the one to be pushed forward? Classic AOS is already an emulated feature on anything more recent than a 680x0.
More than everything, what the Amiga community needs is the support of
developers. Improve the hardware compatibility for AROS and make it cheap to be installed on commodity hardware. Make that platform interesting for developers!
Unfortunately, according to the ~800 voters of this
poll, my thoughts are not shared :-)
