Unfortunately, this is what I use Mathematica for, etc etc... Hello? Gee, unless you want to do something UNUSUAL like NUMERICAL CALCULATIONS...(And what kind of mathematica user would have that in mind....) And compare the native code version of mathematica running on a powerpc macintosh to a student version running under 68040 emulation on the same computer. That is NOT a 4 times slower. Wolfram's OWN ADVERTISING gives numbers like 17 seconds versus 109 seconds (on a Quadra 700, presumably running an enhanced version...) For those with a new PowerMac check out the sample software from Wolfram on the CD sampler. Questions for WOLFRAM rep...(surly mode on...) 1) Will there ever be a native (student) version of Mathematica for the powerpc. Hypothetically, if there was no MacIntosh for sale powered by something other than a power-pc would this be a factor in your policy, or should we just be thankful that Mathematica wasn't first created in the 8088 era? 2) What will happen to the current user base when OS for Mac and INTEL computers become multi-tasking? (Both mac and windows claim that is coming within the next year.) Will you slip code into student version which checks to see if there is a session already running? Is that code already there? As an aside, I have been using Mathematica while teaching my high school math (and computing) courses since 1988-89. I am the leading proponent of increasing computer use, specifically Mathematica, at my current school - Choate Rosemary Hall. While visiting Middlesex academy for a school recertification visit last week, I noticed that Mathematica was installed but virtually unused on their computers. (Note of interest, Middlesex and Choate have both been listed in ads from Wolfram..) I am becoming the math department chair at a third school, Kinkaid in Houston Texas. I would very much like to continue working with Mathematica there, but there is no way I will pay more than $200 per license and, on principle, no way I would purchase any mathematics software which has intentionally been crippled so as not to make use of either an advanced processor or an FPU. Honestly, the only way I would recommend purchasing Mathematica would be to purchase used NeXT workstations which include an academic license. Wolfram must realize that they have almost ZERO penetration of the (fairly) large high school market. I firmly believe that their bottom line would be increased significantly if they came out with a "Mathematica lite" version which used a kernal which actually fits onto a 8 meg computer. Provide the full processing speed and let the schools purchase more libraries as they decide they need them. As for me, MathCad is offered for $49 with the Maple libraries. I don't want to learn a new environment, but I suppose it isn't out of the question either. It's too bad. I've carried a torch for Mathematica for a very long time.
