Although my husband assures me that I'm out of the loop, and that WolframAlpha has been out for at least six months or so, I've only recently discovered the new tool and I'm wowed. This self-described "computational knowledge engine" is a kind of numbers-facts database that also calculates things as well. So for instance, if you type in Cusco, Peru, you will be given facts about the population, maps, even things like the average temperature historically. Other bloggers have referred to it as the Google Killer. You can see a demo of what the new tool can do here: http://www.wolframalpha.com/screencast/introducingwolframalpha.htmlimage: chattahbox.com/.../05/wolfram_alpha_logo.jpg
