If you have a Bluetooth mobile phone and a Bluetooth enabled desktop or laptop (now many laptops come with Bluetooth feature, if not, you can always buy a Bluetooth USB Dongle), you can pair them and use your cell phone as a remote control, browse files, play music and PowerPoint presentations on your computer.
To do this, you have to pair your mobile phone with your computer first, you can find a tutorial here as to how to pair your mobile phone.
After Bluetoth pairing up, you need to download a program called Bluetooth remote control, including a client to be installed on your computer and a small app on your mobile phone to control your laptop. You can find a detailed user guide on this.
