I know that Maps use data from HERE, but the search algorithm it's not as good as on HERE, and until a few months ago the Maps user interface was rubbish. Now it's a better but still there is no alternative to Nokia Drive on Windows 10 Mobile: you simply can't (or at least I didn't find a way) to activate the drive interface without looking for a destination.
Windows Maps is less clever than HERE, for example if I look for a street named "Via Giuseppe Garibaldi, 4" (I'm Italian) often it doesn't show the nearest one to me, but it drives me some other road, often in another city. And I always need to remember to input the exact name of the street, if I just digit "Via Garibaldi, 4" (very common form of abbreviation in Italy) it doesn't show any results or it gets me a completely useless one. HERE worked all the times. It is also not uncommon that number positioning on streets is not accurate; sadly, there were times I had to open Google Maps on Edge to look for the correct position on #34 on the street I was on, because Windows Maps was showing incorrect data and I couldn't find it by myself (that is the reason I was using a GPS navigator in the first place).
IIRC, HERE maps is built by actual navigation rather than crowd sourcing which makes it more accurate than other ones.
In areas with active communities, that OpenStreetMap is crowd sourced is probably more of a strength than a weakness. The issue for OSM is that there are lots of places where there aren't any active contributors, never mind a community.
This tools makes it easy to compare several web maps:
>> both are in a race to become the world’s first Universal Map — that is, the first map used by a majority of the global population
when I had my Windows phones, I preferred the Bing Map app to Google Maps. I always thought the UI was superior and more user friendly to Google Maps.
One reason for the poor quality of Google Maps was the lack of an official App, and third-party ones were quite poor. Google seems to have a policy against releasing apps for Mobile Windows platforms that goes further than just "we don't care".
EDIT: market share http://www.idc.com/promo/smartphone-market-share/os;jsession...
The difference between the Windows phone and Android was pretty huge:
Android text message:
- Message pops up that I have a text message, I have two buttons, ignore or read.
Windows Phone text message:
Voice alert asks if I want to read it or ignore it. After reading it I can:
- delete it
- respond via voice command
- or call person back from number
It's a pretty big difference, and one I really noticed when I went back to my Android phone.
Does HERE have anywhere near the marketshare of Google Maps (>1 bil.) or Apple Maps (~800 mil.)?
