Does that mean by the time Google had decided to work on the iPhone-like Android interface, they had been planning to work on a turn-by-turn navigation system using Google Maps for Android as well?
Actually it depends on how you use GPSs. Its certainly possible to write a mapping/GPS app for a smart phone that is competitive with the more advanced features of handheld or dashmount GPSs, but I simply haven't seen one yet. None of the features I need are big ones, but rather a bunch features that add up to a much better user experience for a GPS geek. A couple of those hard to find features are: multi point routing (or some way to allow me to tell the GPS the route instead of the other way around), ability to build routes on PC/Mac and upload to the GPS, off-road routing, track to route conversion, etc..
