Point taken. However, like I said above, I know a few startups who use python, and the only Windows boxes there are for IE testing. Certainly no-one deploys on it. Academic computing seems to be a different world, though.

While I do lots of web work, the majority of my work with Python is as a scripting language embedded in a cross-platform app (Sublime Text). There are easily hundreds of thousands of developers who use that work on a daily basis.

The Windows support in Python is extensive enough I was able to write a web-client using ctypes and the native Windows network API to better support users with funky proxies and so forth.
