$50 Wolfram Alpha app appears on App Store, appears to be worth it

Wolfram Alpa, a “long-term project to make all systematic knowledge immediately computable by anyone,” recently had their iPhone app accepted by Apple into the App Store. The application—which costs a nicely sized $50—is the first native Wolfram Alpha application available through download in the App Store, although the company has had an iPhone dedicated website for a while. It uses the new API the team has recently opened to allow developers to use the knowledge engine in their own applications and software.
