I prefer Bing only when I'm looking up Microsoft IT items (i.e. how to use a particular code library in .Net).
I only use Bing to get the rewards points. A while back they revamped their rewards points for searches on both computer and cell phone. They stopped allowing you to click on their news scroll to get search points, so I don’t bother worrying about doing the required searches to get the points on my laptop or phone. I rarely use Safari on my iPhone...just use it for calls and text, nothing more. I get Bing reward points only via their dashboard offerings. Bing has a tendency to bring up results for mostly liberal news sources, which is why I don’t take the first searches that show up, but go farther back if possible, and use lengthier search terms to find a source I prefer, if it exists.
