2. Why did they not use a different GPS chip when they know that cold start would take that long?
Which chip exactly? Hardware in devices like this is always a compromise: this TI chip is really small and efficient (and it's already used in Nokia like ag2 said).

The chip may well be a good choice, but I really wish TI/Nokia weren't so paranoid. I mean, not only the driver but also the libraries that interact with the driver have been closed...
