If you're going to learn something new, you might as well start with PowerShell. Theoretically, there's nothing WMIC can do that PowerShell can't do better. http://www.microsoft.com/windowsserver2003/technologies/management/powershell/default.mspx

Granted I'm no developer by any means, but I only use WMIC for very basic stuff like "wmic product get name,version" .
