Which fact? Apple's 100M listings or Google's 80M? I have no idea, but I would be kind of shocked and impressed if Apple had more listings than Google...
Oh please. Apple would/could never block sites in safari... Let's be realistic.
In fact, I'll eat my hat if Google hasn't released a Maps app on the app store by the end of the year. I'll be surprised if Google doesn't have one ready by the launch of iOS 6.
The Google Latitude app is already forced to use Apple maps.
You better get a tasty hat.
