PowerShell is less like bash and more like a .net based DrRacket. You can instantiate .net objects, query their state, manipulate them interactively, and pass them around. You can also trivially write new shell commands in C#. If you go through the tutorials and write a cmdlet in C#, and see how it interacts with powershell, you'll understand why it's cool. Might not be useful for everything, but it's well designed and extremely powerful.
