I just hope whoever buys HERE doesn't screw it up. At the moment I do like them more than the google maps. They are also cheaper when it comes to licenses.
I've heard rumours Samsung is already using HERE heavily internally. So it would make sense- but what will happen to the other that are currently using it to (they've mentioned Microsoft, BMW etc. in the article).
Nokia Maps has almost always been better than Google Maps, it's just not well known. Nokia bought Navteq back in '07 I believe, and I used to use Nokia Maps on my N95, which had A-GPS for fast lock (new tech for GPS-enabled phones back then). People were floored that a phone could find POIs/food and do quality navigation. This was all pre-iPhone too.
Even now the current HERE Maps allows you to cache full countries for offline traveling and a bunch of other small features that add-up to leaving GM in the dust. Full offline caching has saved me in a number of situations. If Apple Maps wanted to compete with GM, they should buy HERE... and rename it to something better. It's been renamed about 4 times over the last 8 years.
Samsung has been slowly building up their own "shadow stack" for mobile. They have everything from the OS up, but map data is a huge missing piece.
Also, I think Samsung's homegrown Tizen OS has some ambitions on the automobile side, and that's a market where Here has been doing well.
