With the maps you actually need deeper integration for defaults. You really need to be able to change the tile source that is used for the maps in the Apple apps.

i.e. you need to be able to swap out the map tiles within Find My Friends, iPhoto and Find My iPhone with another source

And of course that is never going to happen frown

I'm just praying that Apple have something up their sleeves to make their maps actually usable before launch. I'm not hopeful though.

I'd publish examples of how bad their maps are, but I suspect the NDA forbids me from doing so.
