iPhone morphs into PC mouse trackpad
Cool application of the day: a piece of third-party software that lets you transform your Apple iPhone or Apple iPod touch into a wireless touchpad for your computer.
Touchpad enables you to create a wireless touchpad on your iPhone, letting you control the mouse on your computer using just the handset. You can move the mouse around, click, double-click, and even drag items by double-clicking on a file but keeping the touchpad pressed down. You can scroll vertically by click-and-dragging on the right edge of the Apple iPhone screen.
Replaces computer mouse
You can use Touchpad to control videos, show pictures, advance slides in a presentation - pretty much anything a traditional computer mouse can do.
