Thanks for the very clear explanation of this type of duality.
Your last major bullet point (above) raises a new question for me: "dual band base station". It would seem that "n with b/g compatibility" could be labeled by some non-Apple vendors as "dual band", but as you point out, it could be at 2.4 GHz only. Is there are clear way to know if the router can operate simultaneously in both bands (5 GHz and 2.4 GHz) before purchase?
