And it's not "AGPS vs. Sirf Star III". It's "TI chipset vs. <insert any other chipset here>". AGPS can (and should, if possible) be used with _any_ chipset. > The sentence makes no sense. AGPS is not 'old solution'. Completely wrong. AGPS by Motorola A1000 was introduced exactly for the reason gps chip was not Sirf III. What you call instant lock/fix is another type of A2GPS and I say nothing against Sirf III GPS + network fix assistance. But the implemented is old (non- Sirf III GPS chip) + network fix assistance. Exactly the old solution. A1GPS. It's not even a crutch. The way the GPS system works there is _no way_ to get instant lock (particularly from cold start) without using assisted GPS. It's _always_ useful to have AGPS, or any system that does the same (=>pre-loading data that one would otherwise have to wait for). Who said otherwise. A2GPS is ok. A1GPS is not a good solution (for definitions see above). > $10 is in this context an enormous amount of money. Mayby yes mayby not. I got $100 car navigation devicer as touch screen + maps + routing + Sirf III chip included. So I don't see extra $20 for full GPS in N810, iPhone makes any difference for a knowing buyer. " Device producers are always trying to shave off a cent here, a cent there, if they can, because it all adds up to the bottom line. In any case, nobody in this thread will know the authoritative answer to the choices, there's just a good guess that the cost, plus the power (battery) requirements are both lower for the TI chipset. But we're not Nokia. " ok, ok, ok for the same reason I decided not to buy any model of iPhone without full Sirf III gps navigation. " It's probably not much use to keep replying though.. so I won't bother after this one.
