I think many of us who use Windows take for granted the number of tools we use to cover over our pain points.
I use Msys2, Cmder, a bunch of custom tool builds, and some Powershell scripts. This setup works great; I'm productive with it and my command line feels fantastic. However, I have been tweaking my setup for years. WSL makes all of that learning, setup, and tweaking unnecessary.
All of your tools are available out of the box, and you don't have to configure anything, hunt down binaries, or make your own builds.
This isn't about making you and I more comfortable - we already are. This is about making it easier for other devs to find a happy setup on Windows.
