Oh yes, i understand. One tool rarely does it all. I always wanted a copy of Mathmatica, so I'm a tad bit envious. I remember the kids who were doing higher math in 1990/1991 using Mathematica and it seemed like SUCH a powerful program compared to anything else I saw before. I worked in the computer lab, and I had to help tweak the computers so the kids (I say kids - they were "older" to me then - 19, 20, 21) and professors that used it could use it at its maximum efficiency. But I was taking child psychology, pascal programming, and other courses having little to do with mathematics. But I'd see them with their fancy formulas and think, "Man, I should be using the sink, not improving the plumbing". Man, 25 years ago. Yow. I don't even know when Mathmatica came out honestly. It must be ancient - I don't *think* Excel even existed back then. It was Lotus 1 2 3 and.. hm.. Quattro Pro. Wait - the Macs had Excel. Yeah, I played with it on the Macs. Had other friends doing AI, but I DID get to play around with Fractals. My downloaded copy of Fractint was worn out; I'd beat up my poor computer trying to make it do more and more difficult fractals, probably my frustrated response to the students that understand the higher math scribbles that I didn't. But I got to make prettier pictures and see recursive math in beautiful 16 and then 256 color when THEY were graphing in boring black and white. So, I had some vindication tongue emoticon
