Google isn't evil!!!

Google Search: 10458
This seems to be rather noble of them. If you type in a zip code, it doesn't just ask you if you want a map from Google. It also has a link for Yahoo and MapQuest. Even more interesting about this is that Yahoo fairly recently cut off their relations with Google (Yaho search used to essentially be Google rebranded.). Sure Google is listed first, but the fact that they still prominently show the other two (not just based on PageRank) is amazing to me.
