I've not posted anything anywhere, despite having worked for Steve at NeXT in the late eighties, but this thread brought back memories. I was doing developer relations for NeXT, so I was involved in many of the meetings with folks like Wolfram. (Don't get me started on refereeing meetings between Jobs and GatesMathematica was a fascinating program, even in those early days, and I enjoyed supporting Theo Gray, who did the actual port to the NeXT machine (and more recently has created the "Elements" app for the iPad).
I love the
Earlier this year, there was a session with Theodore Gray at the O'Reilly TOC Publishing Conference (page about the session here; YouTube archive here). He tells the story of gathering his real collection of the elements -- at least the ones that are possible to gather -- and "the power of eBay" to help with that.
I've lusted after Mathematica for the last quarter-century, but coud never justify springing for its four-figure price. The instant Wolfram announced the "personal" edition, I jumped on it. I love using it to explore mathematical ideas, purely for my own amusement. This sort of application is a "brain amplifier" - it enhances an ability the brain alteady posesses. I hope to see it on the iPad someday - I think that would be a true embodiment of one of Steve's dreams.
Wolfram has noted that the CDF player will be coming soon to iOS and Android. As far as I've heard, the CDF player is essentially the full Mathematica engine; I don't know how much it would take to provide the capability of the full Mathematica package. Perhaps Wolfram will go with a distributed approach and have cloud resources do part of the work.
Wolfram has some interesting business decisions. Will they work to make Mathematica available to the masses? Or will they keep their authoring tool at premium prices and encourage Mathematica users to publish CDF files? Either way, I hope we have an explosion of people who explore the beauty of mathematics with Mathematica.
