To be more clear, what I meant here is more precisely that the logic which
ends up being used to actually choose which sources (GPS, Wifi, whatever)
for determining the location is sometimes (often?) logic down in the
chipset -- through a location function of the chipset that even down that
level abstracts away which particular means of determining the location are
used (similar to the way the Geolocation API abstracts it out way higher up
at the Web API level) (Of course after that the actual means the device
uses for doing a location query is through some hardware on the device.)
