Sony pioneered portable audio in 1979 with the launch of the world's first Walkman - a single tape playback only device that marked the beginning of a consumer audio revolution. Almost 25 years later, the latest incarnation of the Walkman - the Network WALKMAN NW-MS70D - is just 5cm tall, weighs 54g and holds 11 CDs worth of music on its 256MB in-built Flash Memory.Apart from the obvious benefits of size and weight, the advantage of the solid-state digital Network device over the original Walkman and portable CD players that followed is the completely skip-free performance - especially during active use.Like many of the latest portable digital products on offer, Sony aims to blur the line between fashion and technology with the NW-MS70D - its streamlined design and compact titanium body is billed as a sophisticated accessory that can be taken anywhere, not just on the morning jog.Memory capacity is expandable via a Memory Stick DUO slot (currently up to 64MB of extra capacity) and the embedded internal battery provides up to 33 hours of continuous playback according to Sony.The NW-MS70D Titanium bodied Network Walkman is available in Australia from June 2003 and costs AUD$899.Contact the Sony Consumer Contact Centre on 1300 13 SONY (7669) or follow the links below to learn more.
