Like inquirer said, Google already does math. It also does question-answering, although apparently not quite as well as MSN yet.
MSN recently came out with http://virtualearth.msn.com/, which seems to identify street addresses more correctly than Google Earth does. (At least in Boise, where I live.)
Competition is good. You know that Google is now going to work extra-hard now to surpass whatever Microsoft has done, and that just means more cool features for us.
