It's also great for doing calculus. Give it something like: ∫(x^2*e^x, x) and it'll show you the result of evaluating the indefinite integral, some graphs, other information and the steps it took to evaluate.

IF you can figure out how to properly phrase your inquiries, Wolfram Alpha can do an amazing job of finding and presenting data. All Google can do is show you what exists. Wolfram Alpha takes data and presents it in ways you want – you can ask it for statistical data, such as per capita income or lifespan for a list of countries (or all countries) and it gives you back the list and the information presented as a graph.

If you ask for per-capita income in the U.S. and Canada in Google, you'll get lots of sources that might list one, or the other, or both. If you add two or three more countries, you get a mess. In Wolfram, you get the data you asked for, integrated and displayed graphically as well as a link to the sources.

No – I never paid the absurd $50 price. I bought it a little while ago this morning, for $1.99.

Ha – you beat me to this story. I just bought the app a little while ago – hoping it may come in handy for some of the tough questions my 7 year old daughter fires at me. Google is of course already my / our friend for those, but this app looks like it may be a good supplement to it.
