There are at least a couple 3rd party transit apps available now that support iOS6 maps integration (I tried Embark and HopStop). I figured the integration fed data into the maps app, all it does is launch the 3rd party app. How is this a better solution? Apple is kidding themselves. Why would I bother launching the maps app in the first place if I'm looking for transit directions, I can just launch the 3rd party app.
