I have been using the new Micosoft Bing search engine for about two weeks now and I have to say that it is a fine competitor to Google. David Pogue from the New York Times wrote a much better comparison than I ever could:Bing/Google Comparison. In the article he references a site where you can query both search engines at the same time. I have been using it for the past week and it provides you a quick way to compare results.
