It's just as well. Monad appears to suffer from severe second system effect ( http://en.wikipedia.org/wiki/Second-system_effect ).
The early demos I saw had hopelessly long names, verbose syntax, and attempted to coalesce data into xml. While xml seems like a more flexible target than plain text, the net result was that it took a foreign set of tools to manipulate xml from one command's output to what the next command wanted.
In the spirit of "Get off of my lawn!": I wish that .vbs had been cultivated into a usable environment for interacting with the computer instead of left to be identified with malware. The language is/was certainly more appropriately sized for typical system automation tasks.
The CLI is more than just the shell's capabilities. Microsoft expected people to use PowerShell with the same horrible cmd.exe, and ignore the multi-second startup times.
Then MS delayed it, split Monad (renamed PowerShell) from the OS-that-is-now-Vista, and sat on the technology for a few more years before quietly launching it as an Exchange Server admin tool. Meanwhile, I found myself using IRb and IPython more and more, and never really got around to setting up that Windows box.
