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.
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.
