On the Mac desktop, I still use a creaky ancient app called MathPad. http://pubpages.unh.edu/~mwidholm/MathPad/ http://pubpages.unh.edu/~mwidholm/MathPad/ Really served me well in college. I've heard it referred to as a "Poor Man's Mathematica" back in its day. If Soulver worked more like this, I would have bought it by now. That said, I've found that using my iPod touch as a "real world calculator" is much more convenient, and I ended up buying PCalc for it. http://www.pcalc.com/iphone/index.html http://www.pcalc.com/iphone/index.html Being able to tap calculations while walking and pacing the room brainstorming tended to be more useful than being forced to sit down and type at a keyboard.
