Bing, Google, or Yahoo?

In the arena of world-class search, can Bing bring the hurt to Google and Yahoo? Microsoft's newest search engine comes packed with search tools such as an Explorer Pane for refining searches, Quick Previews for sneaking a peek at a site before visiting it, and Sentiment Extraction for making sense of product reviews.

Google and Yahoo, meanwhile, are no chumps. Google has outwitted its competitors by delivering solid search results and cool tools such as Street Views. Yahoo has done a masterful job of integrating search results with its rich network of Yahoo content. Search for the musician Sting within Yahoo, and presto--you're watching Yahoo music videos or listening to streaming audio of Sting singing "Desert Rose" from within your search results.

How do these services stack up against each other? Bing targets four categories of search: shopping, local, travel, and health. In a highly subjective comparison, I tested Bing, Google, and Yahoo in these areas and in others.
