a desktop trackpad that works like the pads on its notebook computers. It's called the Magic Trackpad, and it gives you all the convenience of a trackpad with all the functionality of a mouse. In fact, the entire Magic Trackpad is a button, so you can click it anywhere. But you can also pinch or spread your fingers to zoom, or swipe to change pages.
This seems like a pretty big step forward. Mice aren't going away yet, but the trend is headed that way.
