Apple files Magic Trackpad trademark

Apple filed for the Magic Trackpad trademark just today with the US Patent & Trademark Office. We don’t have the full details about this device, although Magic Trackpad will most likely refer to an external peripheral device that targets desktop computers and notebooks which are plugged into external displays. After all, with more and more of OS X relying on multi-touch gestures, Apple will most probably offer desktop users a method to take advantage of such a system. Do you think this is just an ordinary trackpad which is taken from a MacBook, or is there more than meets the eye?
