Wolfram Research has unveiled the new Mathematica 6.0, heralding it as their most significant product since its first release twenty years ago . Mathematica 5.2 was already the #1 technical computing software, and was also gaining ground in new market areas, replacing cobwebs of specialized packages. Now I see it replacing loads more software: http://www.wolfram.com/products/mathematica/newin6/ [Broken] IMO the most incredible part is the way that the core Mathematica system has adapted the changes. The goal has always been to integrate as many features of technical computing as possible in a coherent and unified way. In the long run, I think Wolfram Research will be the only ones computing with Microsoft on the unified front, and by the looks of how smooth the current addition of functionality is with version 6, I think they will be come out ahead on the coherent front.
