Do you know anyone who's ever used Google StreetView and said, "Nope, this isn't helpful at all. We need something better."? I don't personally know anyone who doesn't find StreetView incredibly helpful as it exists right now.
Sure, StreetView isn't perfect, but I don't think Apple is barking up the correct tree with FlyOver. StreetView is helpful because it shows me what to expect to see at pedestrian level when I get somewhere I'm not familiar with. FlyOver shows me what I'd see if I were flying to the place where I'm going. How often do I do that?! And the 3D renderings of buildings in FlyOver in many cases just don't look realistic.
To me, it seems like FlyOver is Apple's solution that's looking for a problem. Actually, I think Apple Maps and FlyOver are Apple's solutions to Apple's problem -- with Google. The average consumer doesn't have a problem with Google Maps or Google StreetView.
Over the past decade or so, Apple's been very good at helping the consumer realize that we've settled for mediocre far too long and that Apple can make a better product and a better experience. They did it with MP3 players, cell phones, tablets, and computers. I just think they're missing the mark with maps and navigation.
Like them as a company or not, you can't say Google has put forth anything less than an amazing effort in terms of time, financial resources, and boots on the ground to get Google Maps and StreetView where it is today. In the mapping space, Google started thinking outside the box many years ago and they've only continued to pick up momentum in that space. I think Apple has a LONG way to go if they want to try to top Google's efforts.
