It's a better design, imo.

Have you ever wanted to write a command line executable and gotten hung up on I/o and parameter parsing?

With PowerShell you can write a cmdlet in C# as a PowerShell module and have strongly typed input and output parameters for free. It's a revelation.

As as scripting language, it's fine but for me the killer feature is being able to easily extend it in a non-scripting language.
