I was not aware there was a bing maps. (not a troll, just a random data point).

I agree that apple's effort in developing maps has to scale over a smaller user base than google's efforts, which doesn't encourage the same level of investment. Plus apple doesn't appear to be able/willing to monetize their user's usage the way Google can/does which also increases google's incentive to do a good job.

Honestly, I really like and use many Apple products but I don't really understand their long term play.
