Regarding your point about the Amiga being commercially dead, I guess that really depends on what you mean.
Amiga has been dead commercially for a decade now. It has nothing to do with anyone meaning anything, its just a cold hard fact. Having a Firefox-port does not revive Amiga either, nothing will. Its more of a nice commodity than a part of marketing plan, something for the hobbyists. Certainly not the most important thing atm, not even close.
