Microsoft is taking on Google with their new search engine Bing, which greets you with "Live search is evolving. Welcome to Bing" on the home page. The home page also features a large graphic of a hiker walking through mountains. Besides that there is a simple search box, but there are also options to link to search pages for "images" "video" "shopping" "news" "maps" and "travel".
It is certainly worth checking out. WebProNews has an interesting story about Matt Cutts (the head of Google's Webspam team) Twittering about Bing yesterday.
