Since I am at the Consumer Electronics Show, I thought I'd mention that CSR, who bought SiRF, has announced the SiRFstar 5 chipset which you will start to see in devices later this year. It will have better capability to deal with multi-path in urban areas. It also offers some potential for indoor navigation using dead reckoning and WiFi correction. It is hard to know yet how well this will work. The GPS at least will be improved. We are also starting to see GPS chips which use both the US GPS system as well as the European Glonass system.
The SiRFstar 3 chipset used in the Breeze and Kapten represents 5 year-old technology. It is decent but far short of what you can get with current GPS receivers.
