August 8, 2006 Sony’s next generation sports walkman was unveiled yesterday but with the fanfare surrounding the far more significant MYLO, it’s not surprising that the diminutive S2 Sports Walkman devices might not have seen as much of the spotlight as they deserve, either technologically, or historically. The original Walkman hit the market in Japan in 1979 and arguably began the personal music revolution, with the cassette Walkman selling close to 200 million units before the MP3 player was born. The new S2 Sports Walkman actually offers some unique compelling new functionality for people who are exercising, most significantly the Music Pacer feature gauges your speed, tempo and acceleration, automatically switching to the appropriate personalized walking or running playlist to match your rhythm. The S2 MP3 player is a water resistant aluminum cylinder about the size of a tube of lipstick, weighs about one ounce and comes with its own armband. The 2GB model will cost around US$150 and the 1GB model will cost around US$120 when they hit the shelves next month.
