Was playing around with Windows PowerShell recently and it ROCKS. there has been a lot of coverage around PowerShell so I won't bore you with some of them, here's a great video screencast by Scott Hanselman to get your started on PowerShell.
What I wanted to do was to see how easily it would be for one to write a test harness for automating the instantiation of Device Emulators so that developers and testers can quickly test their application on different device configurations.
This sample uses the Managed Core Connectivity Wrappers that we've built into Visual Studio 2008 and the new Windows Mobile SDK.
You need the following installed before you can proceed:
Here's how you can instantiate a device emulator from powershell.
Step 1: Start PowerShell in Administrator mode and enable script execution by typing "Set-ExecutionPolicy unrestricted", especially if you're on Vista.
Step 2: Load the Microsoft.SmartDevice.Connectivity assembly using the LoadWithPartialName method.
Step 3: Create the DataStoreManager object. "1033" is locale for "en-en"
Step 4: Query the types of platforms that are installed on your machine. This will return the list of Windows Mobile Emulator platforms that were installed together with the SDK. If you have not installed the Windows Mobile 6 SDK, you won't see the Windows Mobile 6 Professional nor the Standard SDKs.
Step 5: Enumerate Platforms and create a collection of platforms in $plat. Assign platform that you're interested in to $wm6, in this case we're using the Windows Mobile 6 Professional SDK. (item 0 in the collection)
Step 6: Get the list of devices for that platform. This shows you all the possible device configurations / types that were installed with that platform.
Step 7: Let's pick the Windows Mobile 6 Professional Emulator by picking device  and connect to the emulator using the $device.Connect() method.
That's it :) pretty powerful. You can imagine how flexible PowerShell is by allowing you to write .NET Code together with Shell code to create automated scripts. You can now easily instantiate emulators and deploy custom configurations automatically to create a full automated test environment.
