One of the very few features I missed after leaving Android for an iPhone was the turn by turn navigation. Google Maps have always been the best, and adding free turn by turn to a great maps app made it unbelievably useful. I've just lived without it up until now because I wasn't willing to pay money for garmin, tomtom, etc. on my iPhone. Now with iOS 6, we'll get turn by turn that's even better than android, because Siri is integrated. The maps are great. Turn by turn is relly good as well. But, the satellite imagery they are using is absolutely terrible (and this screenshot is even zoomed out pretty far).
Take Asheville for instance. It's not a giant metropolis, but it's a large enough city to expect decent imagery. Even small towns outside Asheville are covered by some pretty impressive satellite imagery in Google maps. But as you can see above, even downtown Asheville doesn't have enough detail to even tell what you're looking at. Who knows how long until it's got 3D maps. That said, it is beta, and will be for the next few months, and Apple only has over $100 Billion that it could spend between now and October to get some new satellite shots taken.
Here's to hoping they do, because that image above is unusable.
