iPhone as controller for everything

“Instantly transform your iPhone or iPod touch into an air mouse, trackpad, and wireless remote for your computer! Sit back and surf the web, browse your photo library or control your music player from the comfort of your couch. Our air mouse uses the built in accelerometer to translate your hand motions into mouse movements on your screen. It can also operate as a trackpad, allowing you to control your computer with a single finger. Suddenly your iPhone has become an essential part of any home theater PC and a presenter’s best friend. Using an innovative application notification system, the iPhone will always know what applications are running at any time and show the appropriate keys for that program, providing you with a single screen for controlling ALL your media and web applications.” – http://mobileairmouse.com
