He might be referring to powershell ... I never use CMD anymore.
I first started using it a few years back because it uses 'ls' instead of 'dir' for a directory list. Over time I've learned more and more about how its improved over CMD... and it has gotten even better in windows 10.
May not quite be 100% as good as terminal on OSX but it really is very good.
Funny annecdote. I was at a clojure meetup last night tapping away on my windows 10 laptop and the developer behind me said "is that Ubuntu?" I told him that it was W10 and he said "wow, I guess I might finally have to admit that windows doesn't look terrible anymore"
I felt like that was pretty high praise given the audience.
