Sony's Focus on Building High Quality Media Devices

Sony has long focused on building high quality media devices. The value of services and the value of intellectual property far exceeds their ability to manufacture new cool devices, right? That never ending hunt for the new Walkman that made them famous in the early days eventually is going to run out of steam as they have to focus more on becoming a media empire of sorts. Sony is also one of the companies that has the least developed multiplayer components.
