If you play all or most your music and videos on your computer or laptop you should have a look at the Hauppage Windows Media Centre Remote Control Kit. You plug it into a USB port, set it up and use the remote control for all the Windows Media Player settings such play, pause, rewind, next, record, etc.
This is really nice especially when you link your PC to a big screen at a presentation or at a party. As you can see on the picture, the remote control device is fully featured. And the price is only R378.
