Just like when a startup bases their existence on (say) the Facebook API, becoming part of Microsoft's ecosystem has a lot of benefits : But there are significant downside risks. I think it's already telling that you're interested in Django, Rails and Vim. AFAIK, they're all built by *NIX people (even if they're using MacBooks), and treat supporting the Windows platform as a necessary evil. From my point of view, it's better to be on the side of contributing to a global software ecosystem, rather than one owned by a specific company.
