Though the wording on the box claims a Mac is necessary, we successfully paired the Magic Trackpad with a Windows PC. That said, you can actually use Apple’s Magic Trackpad with your Windows desktop. There’s absolutely no mention of Windows anywhere in the specs. The stuff looks tempting but Apple’s marketing brochure clearly states that you need a Bluetooth-enabled Mac computer running Mac OS X Snow Leopard in order to use the Magic Trackpad. You can use two fingers to scroll pages while swiping with four fingers will let you switch between open applications. The multi-touch enabled Magic Trackpad has no buttons but you can tap anywhere on its large surface to click or double-click.
It is wireless powered by two AA batteries and connects to your desktop computer or laptop over BlueTooth.
Apple’s Magic Trackpad appears to be a much more ergonomic way of controlling and interacting with a computer sans the traditional mouse.
