The Fly Pentop Computer and FLY Fusion Pentop Computer are personal electronics products manufactured by LeapFrog Enterprises Inc. They are called a "pentop" computer by its manufacturer, because they consist of a pen with a computer inside. In 2009, LeapFrog discontinued both the manufacture and support of the device and all accessory products, such as notepads and ink refills which are required for continued use. The inventor of the FLY Pentop, Jim Marggraff, left LeapFrog and founded Livescribe in January 2007.
