I guess its already a win if we dont see the brandname abused on low-quality crap ala Commodore.
Amiga & its IP are largely DONE, atleast for the desktop-market. From a hardware POV its senseless to even start investing. If I were to start a new Amiga-like OS I would rather start using AROS and aim at embedded devices. it sure wont compete in the desktop-world, it doesnt matters if x86 or PPC, but it could compare favorably on handhelds/mobile phones, etc which dont have an vast array of existing software.
