Sony 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 adapter to enable use with standard size Memory Stick compatible devices–as well as the Duo size compatible products.
