What makes the price tag even more gagging is the cost of the system being replaced (in 1990 dollars) was $55 million or thereabouts. Which brings me to the reason for the blog post. Once you commit to the Motorola dragon, you are hooked for life. Go ahead and name five other large mobile radio providers in the United States? The only other major one that comes to mind for me is Ericsson.
It might be possible for King County to replace its existing Motorola system with another company, but the upfront cost would be very expensive. In my mind, there's not enough competition in the public radio spectrum and without that competition it allows a single company to dictate.
