I'm sorry but you iOS users are so used to a sub-par Map experience on the iPhone that you actually are blind. Let's face it, at this point, anything Apple gives you would be welcomed with open arms because you have no other choice. Your current (Google) maps can't do turn by turn navigation. Please don't tell me the directions list it gave you (a la Mapquest 1999 printout) is the same as turn by turn GPS navigation. And who wants to buy Tom Tom or some third party paid software when, really, you should be getting this with your phone.
You suppose a "cleaner interface" is more attractive? It's "less cluttered"? When I look at a map, it's because I am lost or am not familiar with that area. Imagine you are in Manhattan and you are trying to find a restaurant. You call them up and they ask where you are. You can't tell them you are 1 block west of a subway or bus stop. You can't even tell them that you are south of King St. because it doesn't show up on the map.
