Something I wish I had in high school

Besides a girlfriend, that is.

I think this has been around awhile, but I just discovered it today. Microsoft's sarch page now includes something called Encarta Answers, which can solve problems with variables! Example: x^2 + 4x - 17 = 32. You need an Encarta Premium subsciption to use it to the fullest, but going through MSN search gives you a two-hour "pass" to some features. Pretty nifty, and a step up from the also-handy Google Calculator.
