What it does is – adds a full-fledged set of gestures, giving you a new angle towards control and interaction to what you are accessing on your Mac. Earlier, this same technology was used in MacBook Pro and was accepted globally. It has a feature, where you swipe your finger over the track-pad to kind of swipe through the online pages of an eBook or magazine. The newly-built inertial scrolling has made moving up and down a page even more natural. The Magic Track-pad is not wired, but connects to your Mac through its Bluetooth technology. The best part is – it can work along with your mouse or without one.
After a few days of usage, you might not even like to use your mouse. The smooth, scratch resistant glass interface makes it easy to access. At the same time, it is approximately 75% larger than the Track-pad inbuilt in MacBook Pro, which gives you ample room to perform various gestures. The entire Magic Track-pad is a button, because of which, you can click on various icons similar to a conventional mice. Apple has also paid quite a bit of attention towards the look and feel of the Track-pad. It is made in the same pattern and height of the Apple wireless keyboard, so you can move from the track-pad to your keyboard in one single motion.Source: www.hackingalert.com.
