Have you guys tried Wolfram Alpha?

It can't compete with Google et al for internet searches, but if you want a quick comparison of data sets for weather, size, numbers etc. it beats the pants off the competition.

Bing does a decent job with flight searches and locating flights that are already in the air. Other than that I really don't know why people would use it.

Bing is easily the worst of the search engines. Whatever they are trying to do with that, they should just start over.

Pretty soon, Google is going to be synonymous with "Internet", like kleenex to tissue.
