Maybe in AUS and NZ, but not in the US. You can pick up various Tom Tom ONE models for < $120. And that includes a mounting kit and charger.
I'm all for integration, but not at those prices.
I think CoPilot price point of $35 is closer to the mark, but eventual they will find a < $20 sweet-spot.
Last December TomTom units were selling for about $70 - new, not refurbs.
Pricing above that would be ridiculous for the software installed in a phone - a PHONE!
