There is already a full featured (including autocompletion), stable windows CLI called ConeEmu (available at http://code.google.com/p/conemu-maximus5/ ).

Also, cli in wpf ?! Come on....

I mention ConEmu in the Kickstarter post. It is an excellent alternative. As for using WPF for a CLI, I think it adds some useful features. At the end of the day, a tool either makes your life easier and you more productive, or it doesn't. I think this tool can add a lot of value.
