The Magic Trackpad is just one of Apple’s latest offerings in the Apple Store. Magic Trackpad is a trackpad made for Mac desktop computers. What’s so special about this trackpad is that it uses the same multitouch technology that is being used on MacBook Pro. In addition, it’s 80% larger than the built-in trackpad found on a MacBook Pro.
The Magic Trackpad connects with your Mac desktop via bluetooth technology. Thus, it is important to make sure that your Mac’s bluetooth works. This will work with Mac computers that have Mac OS X v10.6.4. Magic Trackpad is powered by 2 AA batteries.
I’d recommend for you to use rechargeable batteries rather than batteries that are good for a one time use only. This accessory is available in the App Store for $69.
