This is a fairly major update to the Bing Searchs and Maps chapter, and as you'll see, the end is in sight: The first draft of the chapter is nearly complete.
This version completes the Bing section, though I wasn't able to add some figures because my screenshot app is crashing for some reason. (Doesn't matter: We'll have real Windows Phone 8 handsets with built-in screenshot capabilities just days from now.)
I've also written most of the Maps section of the chapter, adding parts about location finder, inside maps, search, directions, configuring the view, favorites, and offline maps. Only two sections, Outside the app (system integration) and customizing Maps, are left. I hope to finish this (i.e. finish the first draft of the full chapter) today.
