It's game over when this happens. Windows CE is awful compared to Android, and as a plus, Android is built from the ground up with network, GPS, bluetooth, and audio integration. Google Maps Navigation has come a long way and is really nice on my Evo. Can't see why it wouldn't make a great interface when built into the dash. The OS and all of this "stuff" also run very efficiently on a low power ARM core.
Basically, my Evo does everything that my F700-BT does (one in each car installed, too, I'm not a troll). It's just currently in the wrong package/form factor.
