It makes sense. Though, what happens to all those Air Port base stations and such? Would their names be changed too, eventually?
I doubt it. AirPort on the mac isn't needed and serves to only cause confusion for switchers. We all know what Wi-Fi is, but switchers wont have a clue what AirPort is, for the most part anyway. The AirPort Extreme and Express are product names. Changing them to Wi-Fi would make no sense in that case.
