I know that this might strike a nerve with some folks, but what I would really like to see if an app that uses Bing maps. I am a huge fan of Google maps, too but with the Bing map viewer on the PC, you are allowed to annotate the map and write out KML vectors from it. Google maps do not allow that currently and the decision seems to be conscious as it allows you to export KML. I haven't run into pros and cons of using Digital Globe (Microsoft's source) vs TeleAtlas (Google's source.) A google map app that you can annotate and save to My Maps would be as attractive as a Bing maps app that does the same thing. I have a hope that WinMo 7 phones will support this, too. The Bing search engine is pretty tacky looking but is nice and fast. I used to feel this ay about Google search, too but it was too useful to judge that way.
