Nice. I'll have to check that out at home, but I need a commercial license at work, and the rating does put Tableau a little higher (and I've been impressed). Tableau is pretty well priced from my experience, but this thing does come with a lot more license variety.
Since I was totally blown away with it, I'll add WinPython here. I use Windows at work, and even on Linux, getting a Python package manager to work right (especially for Python3.x) or IPython with the QT Console and Notebook just isn't intuitive, straight-forward, or entirely functional! Yet, WinPython, at least for Windows, was such a breeze! It's about 10-20x larger in file size (pushing 300 MB if I recall correctly), but it's worth it.
QT Designer and a bunch of other things (Make custom Python GUIs in a Window builder! Nice!!)
Spyder (and Spyder Lite) for IDE
Python 3.2 64bit with all the major scientific Python modules (NumPy, Pandas, scilearn-kit, matplotlib, etc.)
Portability! You don't need admin rights. It's entirely portable, which is good for me. Well, was. I can get adminity (TM) whenever I want now.
WinPython Control Panel - That's right, it has its own CP for managing packages (just DL the tarballs/exe I guess?) and you can register your portable version so it's like a full install.
Then if you look in its directory tree, it has a bunch of other stuff. I'm pretty sure I saw SciTE in there (which I sometimes use for stuff). It's a great Windows package of just scientific coding awesometude. Get yours today!
