Microsoft realising it now they completely big missed opportunity in web searching. Of course now Google have capture almost 80% of search engine market. I would say Microsoft is still picking up in search and maps. Microsoft always comes-up with additional new ideas which other might have missed, after all Microsoft is investing lots of dollars in R&D.
Personally I like Bing search when it has now filter in search result like ranking, size wise photos etc. Bing map also have "Bird's eye view" which is really good to have feel of any area but it is still not fully developed as google's street view. I am sure now in Microsoft Vs Google competition netizen will get benefits.
