Assuming M$ is always evil is still a personal opinion, doesn't mean it's bad. Replace M$ with Google, Apple, Amazon or any other company doing the same thing, does it actually bring out any meaningful conclusion?

I assume better Ardruino support on Windows is a good thing.

Going from past data, though....

Arduino on Windows so far works pretty well as-is.

IMO some huge potential is missed by the community's collective lack of interest in leveraging Processing (or any other similar thing) to make GUI + open hardware goodies. MS has the potential to do some good here by integrating in an open source friendly way, or they could attempt dirty tricks. I'll encourage/hope for friendliness and interoperability.
