WP8 Maps UX Questions

If you have an 8X or 920 I was hoping that you could tell me what the user experience is like.

- Is the voice turn by turn removed from the default map app

- Does the UI look the same for Bing maps and Nokia maps?

- Do I still have to tap the screen to get the next set of directions

- 8X Users....what happens if I ask for directions? It looked like on one of the video that this feature was taken out, and replaced with a drive to link that opens up a 3rd party navigation app ( or Nokia Drive when it gets released )

- Is it possible to uninstall Nokia Maps and get the default Bing Maps
