Question: What is a small network appliance and entertainment device that serves as a the media player for the iTunes Store?
Context: A middlebox or network appliance is a computer networking device that transforms, inspects, filters, or otherwise manipulates traffic for purposes other than packet forwarding.  Common examples of middleboxes include firewalls, which filter unwanted or malicious traffic, and network address translators, which modify packets' source and destination addresses.  Dedicated middlebox hardware is widely deployed in enterprise networks to improve network security and performance, however, even home network routers often have integrated firewall, NAT, or other middlebox functionality.  The widespread deployment of middleboxes and other network appliances has resulted in some challenges and criticism due to poor interaction with higher layer protocols. A unidirectional network (also referred to as a unidirectional security gateway or data diode) is a network appliance or device allowing data to travel only in one direction, used in guaranteeing information security.  They are most commonly found in high security environments such as defense, where they serve as connections between two or more networks of differing security classifications - also known as a "cross domain solution."  This technology is also found at the industrial control level for such facilities as nuclear power plants, electric power generation/distribution, oil and gas production, water/wastewater, and manufacturing.

The Juice Box is a low cost multimedia player made by toy manufacturer Mattel.  The player features a 2.7 in screen with a native resolution of 240×160 px and runs μClinux, a microcontroller version of the Linux kernel.  It was made and released in November 2004, and was discontinued in early 2005.  It has 66 MHz ARM7TDMI architecture Samsung processor S3C44B0, 2 MBytes or 8 MBytes of RAM and 8MB of ROM.  It was marketed as a portable media player for kids.  The player only played a proprietary cartridge format.  Nickelodeon, 4Kids Entertainment, and Cartoon Network put some of their shows on cartridges.  However, the small screen and poor quality (6 frames per second maximum) alienated most people.  Furthermore, the device entered a crowded market.  Its rivals are the VideoNow and the Game Boy Advance, the GBA being the most potent.  The difference is that GBA not only had TV shows (which can be played through Game Boy Advance Video cartridges), but could also play video games, as it was built for that.  Thus many retail stores were left with a surplus of the device.  Original retail price was about US$70.
