Infinite Math Recognition

The Math Input Panel in Windows 7 and much more:

Have you ever written a math paper in Word or performed calculations in Mathematica, and spent hours creating equations using a multitude of buttons or a complex linear format, thinking: “Oh, what I wouldn’t give for an easy-to-use input method?” Well, your wishes have just come true, in addition to improving handwriting in Windows 7, we have also invested in recognizing ink drawn math equations.

Some years ago, I had to provide solutions to a few calculus problems in a Microsoft Word document. It was a hideously slow process. I wish this superb technology existed then.
