This look great! Will give it a try. On Windows I've been using WinPython

http://winpython.sourceforge.net

which has the additional advantage of being a portable installation. If i'm not mistaken, the same people are behind WinPython and PythonXY.

+1 for WinPython.

WinPython has indeed been created by a core developer of PythonXY, using his experience from PythonXY [1].

Key advantages: (A) Portable version allowing indefinite number of side-by-side installations, (B) Both 32-bit and 64-bit versions are available for both Python 2 and 3.

Downsides: Windows-only

Anaconda is certainly portable on Linux (all in one folder - set the bin path and everything just works), and I think elsewhere too.

Yes, Anaconda is designed to be portable on every platform we build it for, as are all the additional packages that we build for it.
