Wolfram Alpha Arrives On Android For A Very Reasonable $US2

When Wolfram Alpha first showed up on the iPhone last October, it spent a good six months costing $US50. That was not sane! With the launch today of the app's Android version, they're locked in at a perfectly rational $US2. For a compendium of factoids, weather patterns, computational models and yucks? I'll take it.
