Anyone seen that? It's really, really cool. I love the thing and am using it with my calc homework. Major neatness in all the stuff it can do, it isn't too great at explaining the significance of things (It lists George Washington as "Head of State" and gives his Birthday and Date of Death and that is his article in it's entirety) but it is awesome for running calculations and returning stats (You can look up the current weather of anywhere and see graphs of said weather over the last couple years and there's a "Am I too drunk to drive?" calculator).
I highly recommend checking this thing out, even if you're past the point of needing it (Honestly you could use this thing at any level of math or in daily life, so if you can't find a use for it you're probably in a comatose state)
