I've written several times about Bing's chances of increasing search market share through various avenues. While nobody expects Bing to overthrow King Google anytime soon, those chances are pretty good. One of the keys I've repeatedly referred to, is the launch of Windows Phone 7, which will make Bing the default search option. If these devices take off, they could help push Bing's share tremendously (not to mention the company's deals with Yahoo and Facebook).
