Would you really though? I mean, yet another 68k based processor in today's PPC world??? I dont think I would. I dont see how it can be that hard to take the PPC on a board similar to that of Apple's (or a clone, like PowerComputing) add a more amiga like firmware/bios; throw amiga os onto it and call it the AmigaOne or A5000 for that matter.
Maybe I am naive, but ignorance is bliss.
