If you use Vista and you use the Sidebar, Andrew Peters has a neat gadget that hosts the PowerShell Console in your Vista Sidebar. You can download it here: http://andrewpeters.net/wp-content/uploads/PowerShellGadget.gadget.
If you are interested, you can rename the file to a .zip and see what’s inside a gadget file. The cooler bits of the gadget, though, are in a DLL.
