I saw a demo internally today of a new feature in Live Search that I liked. Apparently you can now start searching in IE8's search bar and you might get an "instant answer" as a suggestion immediately.

  

It'll even do things like arithmetic 🙂

BTW... in case you didn't know, the "search suggestion" feature is implemented using OpenSearch, so it's not specific to Internet Explorer. Here's the "suggestion" feature on Firefox. It works with Google as well. However, the "instant answers" seems to have been implemented only by IE8 as far as I am aware (but it's open to others).

 

Update: Apparently the feature is available only in the US at this stage 🙁
