Which is more important? Turn by Turn Navigation or Street View? Just wondering because some people here keep making a big deal about Street View saying the new Maps app will be a downgrade when most people I know didn't even know Street View existed on the iPhone. I know I hardly ever use Street View (like almost never) but I certainly use turn by turn navigation all the time with Navigon and Waze and would use it even more if it was built into the native Maps application. So which is more important to have? Does turn by turn navigation make the new maps app an upgrade?
