it's going to be a while before it becomes a good application.
i am curious to see how fast they can correct the mistakes.
i live in NY so the maps are essentially correct.
3D view is very iffy especially as far as bridges, parks and anything that is not manhattan is concerned, but it is also more eye candy than anything.
turn-by-turn i haven't used yet, so i can't judge.
what is abysmal is the integration of the locations (subway stations, bus stops, schools, hotels, gas stations, restaurant, cafes businesses in general)
they are all wrong. and by 'all', i mean ALL.
in my immediate neighborhood, the maps shows maybe 20-25 'locations'.
a few (including a school, the subway station, a starbucks, a bar and a cleaner, a supermarket) are in the wrong location (off by around 50-200 yards)
the majority (hotel restaurants, gas stations) are business that DO NOT EXIST at all here, some correspond to venues that are IN OTHER TOWNS, but which happen to have a similar address.
in addition there are dozens of venues that are not indicated on the map at all.
i have been reporting these every day (and the reporting system is slow and inefficient, without enough options, so i doubt people will be embracing it), but so far no changes have been implemented.
we'll see how long it takes to correct at least some of them
