Nice side features don't change the fact that the heart of Bing, the search engine itself, is crappy.

About market share
A thing that one doesn't notice immediately is the Symbian ranking: Symbian used to be the market leader of both lower end cellphones and smartphones, but when Windows got its temporary smartphones leadership, Symbian was still the overall market leader, but it had already dropped to 4th place in on smartphones only and kept on dropping in market share, and also in ranking as new competitors came: by the time WP7 was released, Symbian had already little relevance left not only on smartphones , but in the whole market, so there is little left that WP7 can pick up from its remains, and it had been very little anyway for years on higher end smartphoes even when Symbian was still leader in the lower end and overall.
