This week, Sony will begin shipping its awkwardly named Network Walkman Digital Music Player in the United States, in 512MB and 1GB models. Available for about $150 and $200, respectively, the NWDMP (ahem) is about the same size as the market-leading Apple iPod shuffle but offers a number of important enhancements. The first and most obvious of these is Sony's amazing three-line organic electroluminescence display, which is too gorgeous for words. But in contrast with the iPod shuffle, the Sony device adds an FM tuner, a whopping 50 hours of playback on a single battery charge, and a time/calendar display. Also, the Sony devices are available in a number of colors and not just always-dirty and so-yesterday white. Will Sony unseat the iPod shuffle? Frankly, these devices deserve to be best-sellers
