Sony Europe's Recording Media & Energy (RME) division announced the launch of the new 4GB Memory Stick PRO Duo. Sony Memory Stick media are available in capacities ranging from 128MB to 4GB depending on their format (Memory Stick, Memory Stick PRO, Memory Stick PRO High Speed and Memory Stick Micro) and are easily identifiable through a revitalized Sony packaging design, incorporating color coding for easy identification of the different format line-ups as well as the different capacity. In addition, all Memory Stick Duo and PRO Duo media now come complete with a standard size Memory Stick adaptor to enable use with standard size Memory Stick compatible devices - as well as the Duo size compatible products.

The increased storage capacity of the 4GB Memory Stick PRO Duo media enables the users to hold large amounts of multimedia data including digital photos, music files, videos and games as well as increasingly popular podcasts and video blogs. Users will be able to store up to 1000 MP3 songs, 3000 digital photos in 5 megapixel resolution or more than 9 hours of MPEG-4 video on a 4GB Memory Stick, making it ideal for mobile entertainment - especially given the increasing number of available data hungry applications.
