On January 17, 2013, the US Patent & Trademark Office published a patent application from Apple that reveals a new product in the form of a removable device clip. The advanced clip may offer tactile buttons or a transparent glass touchpad. The clip could be used as a remote control. The removable clip could be applied to an iPod, iPhone, iPad, MacBook and yes, even a "convertible notebook." If you like to bring your iPod or iPhone to a workout, the clip will be able to provide users with an added level of convenience with quick to control buttons. The clip will attach to devices via a magnetic mechanism.
