At work Win 10, we heavily depend on niche Windows applications for the whole development lifecycle, even though we use MYSYS for our compilation environment.
For most of the stablished industries changing or altering the development lifecycle toolchain OS is not doable, as it would mean doing a lot more yourself or losing competitive edge by diverting more resources to developing your own tools. Though we definetively have our own development and design tools.
For personal use I use Linux.
