Allow me to be the voice of dissent here.
The poll question is should Microsoft buy Here. Not if I want to. When you look at mapping, the question becomes what is the value verses the returns? In buying the Nokia handset division, you got manufacturing, supply, research and development, access to all of Nokia's patents already licensed, and also prevented your largest supporter of Windows phone from branching into another OS when it was almost 90% of your sales. It was a "had to" buy.
Mapping is a different story. At the price it is being offered at, you could dump half as much into your existing mapping tech and improve it tremendously. Let us not forget: MS is a service first industry, and it's largest selling point is that you can get all the services you need from it. Cloud, documents, mobile, mapping, gaming, music, video streaming: all available. These services all do not need to be the best- just competitive. Bing maps is competitive. Not nearly as good as Google Maps, but a very good service. I am sorry, but Nokia's mapping service is not "better" than Google maps either. So by purchasing it, MS really is not getting a better position in the mapping marketplace than it would have without it, even if it beats Bing maps.
There are only real 2 real arguments I could make for the purchase:
1) MS buying it keeps it out of the hands of their competition. But again, at the price it is being shopped around at, that argument is not cost effective. MS has enough pokers in the fire. Let this one burn out someone elses pocketbook.
2) Bing maps blows chunks everywhere in the world not named the US or Canada, HERE maps is great in every market. I am okay with this, except that I go back to the fact if invest 1-2 Billion in your mapping tech, you can improve Bing maps in house. That is still way cheaper.
As I like Nokia's service better than Bing Maps, sure I would like MS to get it. But I ain't leaving MS to follow HERE maps. And Apple/Google users ain't leaving to get HERE maps. either
