Sony Japan have announced a bevy of new Walkman PMPs, the NW-A840, S740 and S640. The A840-series gets an OLED display like its X-Series sibling, but in this case its a regular display rather than a touchscreen. Still, it manages to be the thinnest Walkman to-date, at just 7.2mm thick, despite that 2.8-inch display, up to 64GB of storage and a battery apparently good for up to 29 hours of music playback or 9 hours of video.
