WolframAlpha has an App

WolframAlpha, the computational knowledge engine, has an application for the IPhone. What has received much of the early publicity is that it is expensive in the odd expectation world of the App, where many excellent and some extraordinary free apps make everything seem inflated. WolframAlpha costs $50 and that's infinitely more than free. I have seen myself hesitating about buying $0.99 applications. There is no logical economics here, or perhaps anywhere.
