Are you one that uses your plasma or LCD TV as a monitor.
Do you know that your Wii controller can be used to control the cursor arrow, open/close new programs etc?
If your PC is bluetoothed, you can do so using the WiiRemote 
Mac PCs can also do so through a related software called Darwiin-remote.
