Whilst I am glad to hear about ConEmu; I have to disagree, I use windows cmd.exe very regularly, and know lots of other people that do, and I have never used ConEmu before! I might give it a try now I know about it.
- Clink is for cmd what PSReadline is for posh.
- posh-git does what git for windows does (I personally don't like git info in my prompt, so use neither, and have a custom, Unixy-one)
