Wolfram|Alpha : computational knowledge engine

I read an article about this program that I will call a "search engine" for easy description,in Newsweek this week, flying back from Jo'burg...and haven't been able to stop playing on it.
Today's WolframAlpha is the first step in an ambitious, long-term project to make all systematic knowledge immediately computable by anyone. You enter your question or calculation, and WolframAlpha uses its built-in algorithms and growing collection of data to compute the answer.
Is WolframAlpha a search engine?
No. It's a computational knowledge engine: it generates output by doing computations from its own internal knowledge base, instead of searching the web and returning links.

Is WolframAlpha free to use?
Yes, it's free for personal noncommercial use .Subscriptions will be available in the near future with enhanced features for large-scale and commercial use.

Who is WolframAlpha for?
Everyone! Its goal is to bring expert-level knowledge to everybody.
