I understand why people use it, but I still think it's incredibly unfriendly for command line usage and I generally don't care about portability to windows.

Moreover, I should articulate, I don't understand why we cannot have the best of both worlds if making a build system is not particularly difficult. I find the fact that it's not particularly easy to set up cmake makefiles as a mark against it, for instance. Autoconf is just ./configure, if the script is set up. If it isn't, you just run a few gnu commands and boom, it's set up. 

Furthermore I'm not saying that windows isn't important in the modern day, but I am saying that Microsoft has been stubborn about being more compatible with unix-likes and abandoning working tools for that is.. dumb. I have never used VXworks or any embedded or non unix stuff out there, so I can't speak for how common it is or how paramount using it is, but it seems that at least baseline posix compatibility is pretty widespread, as is a functioning command shell among most systems nowadays.
