The other day I was watching a good intro video from Shane Young on getting started with PowerShell profiles. I use profile scripts extensively, and they can be extremely useful in configuring your PowerShell experience. One element you could add to your profile is a customized PowerShell prompt. Microsoft provides one by default. It creates a simple function called prompt. The best part is that you can define your own function called prompt, and PowerShell will run it every time you hit enter.
