Wolfram Research comes on stage with Mathematica. A couple months old, but for the technical computing crowd, this is a wonderful, wonderful thing. Also useful to calculus students. Also very funny goy demoing. He had an integrals joke. I laughed. Said he was rendering animations on his PowerBook in the background for like a week. Wouldn't do it on any other OS, because these things need to run for a long time without failing. Also commended OS X's Quartz graphics engine for providing awesome rendering capabilities for equations. The animations were very cool. 🙂
