I downloaded it, but despite the positive reviews, I think the App needs work. I live in Ann Arbor Michigan. I tested the app on two less than 20 mile local trips, while also having Apple's Map App going at the same time.
The app is not the easy to figure out how to use, the app forgot to give me turn by turn directions several times, it fails to auto correct a route appropriately, it doesn't integrate with contacts, doesn't work with Siri, and doesn't look as pretty.
Some of those problems aren't Google's fault (lack of working with Siri), but most are.
So even though I downloaded it, I will keep using Apple's own Map App and my Navigon App.
