Japanese company Quixun announced an interesting system that allows you to control your PC from your phone in certain cases. If your PC comes with an IR port, the keypad of your phone and the directional pad can be used to replace the keyboard and mouse of your PC. Quite impossible for some applications, but when it comes to simple browsing and web surfing, you can easily sit back on your couch and hook up your PC to the TV (or use a PC/TV combo), and enjoy the web without having a full keyboard and mouse near you.
