MS Ba-da-BING

Microsoft is launching it's new search engine: Bing.com
It can't be any worse than Live Search - which is awful. Competing with Google is always going to be a challenge. As I've blogged about recently Wolfram-Alpha is taking on the search giant, but with a different slant on searching.
Bing will try to be intelligent about searches, by using the current date, time etc. to make your search results more relevant. It will also provide related search results and search terms.

It's explained well with examples here:
