Finally got my iphone 5 and tried it out this weekend. As mentioned above, the
3d satellite view is great. Much better than Gmaps as long as the data is correct. But what really sucks for me is the way the maps show road names.
You have to be so far zoomed in before the road names appear, then you can only see that road and none of the surrounding roads. If you zoom out enough to see a few roads, the names disappear and the roads become so narrow and faint I can see them.
It was pretty much useless for me to try to tweak a route on the road since I couldnt ever see an overview with road names. I can see Apple fixing the data set eventually but I have a feeling this resolution issue will stick around.
