I'm tempted of getting one. However, I would first like to see what kind of dock Navigon is going to release. I'll bet it cheaper but still I would like to see some GPS enhancment features like an built in antenna on the dock. I honestly think adding another GPS chip is just over kill on TomTom's part since at least the Navigon app seems to be getting the signal just fine with internal chip so adding good antenna should make it robust enough for some serious navigation.
