Few decades ago MS-DOS CLI was the only shell available on PC. Many of my friends do not want to hear about DOS shell even though they daily use Windows OS in their corporate environment. People trying to escape Microsoft, jump into flashy Apple world and quickly are obliged to use VMware fusion to get a piece of Windows OS to run non-converted Windows applications; what do you want Microsoft is dominant :)
It is true that DOS shell is limited for scripting and people use alternatives such as Perl, Python, Ruby, Groovy, Cygwin, etc. in Windows environment. But with Powershell, Microsoft is trying to catch up by providing a decent scripting language to administrators. With Powershell it is possible to instantiate .Net classes and access Windows OS API; that is indeed powerful for Windows environment. By adding DC network API to the mixture you get the perfect trio for your data center. Indeed, you get an OO (Object-Oriented) scripting environment where you can monitor the status and health of network resources (devices and servers), automate network and server tasks, and get events/alerts to conditions that impact network resources. These OO scripts can be seamlessly plugged into your existing environment to manage your DC network infrastructure. See the video and screen-shots below.
For the video use 720p HD and full-screen to see the shell detail.
