apple doesn't need a web version of maps. only reason google did it was google maps started before smartphones
apple already has diagnostic software in the iphone along with the wifi location mapping database to automatically improve their maps
I would argue that they do. Limiting it to iOS devices can make it annoying if you always have to go threw an Apple device to look at maps. Google maps for example I can find and look for places threw the web on my laptop. Then turn around and push that same information to my phone. It makes getting direction really simple as lets face it computers have much bigger screens and it is easier to type on it.
