I'm still wondering *why* we need to use an AGPS device that's so dumb
that it needs the *host* to do most of the calculations, when we could
have used a SIRF-STAR III sensor, that does everything inside, just like
the GSM/GPRS module.
this sounds like this thing is the winmodem / winprinter of the GPS world
Well...

Is an interesting possibility that might not be possible with that method.
A 'proper' GPS is more expensive, and the calculations are trivial. The
processor has to be on anyway in order to recieve serial data from the
GPS, so there isn't really a downside. (once it's reverse engineered).
