I'm going to compare the iPhone 4S to a GPS unit.
iPhone:
-Does more than give you a map & directions.
-Access to a 3G network allows the phone to have up-to-date business listings.
-Thanks to Siri, you don't have to memorize a set of voice commands.
GPS unit:
-Dedicated to giving maps & directions.
-Works even in areas that lack cell coverage.
What feature would the iPhone have to have to convince you to get rid of your GPS unit or not buy a GPS unit?
