Sony has a few new network walkmans out there, and one of them is the Sony NW-E002F. Part of the Walkman E series, the NW-E002F comes with 512MB of memory. It is equipped with an FM tuner as well. Claiming it as an excellent value-device, Sony assues us it can play for as many as 28 hours on a full charge.

One of the other interesting features of the NW-E002F is that with just 3 minutes of charging, you can enjoy up to three hours of playback - just ideal for those short flights. Some neat battery saving features are built-in, like the power saving Super mode when the equalizer is not in use while playing ATRAC3 132kbps audio.

Another battery-saving feature is the no-nonsense one-line organic LED (OLED) display. This bright display offers English, Simplified Chinese and Korean interfaces. Weighing just 25 grams, the NW-E002F measures 24.8mm x 79mm x 13.6mm. Supported formats include ATRAC, MP3 and WMA.

The Sony NW-E002F player has a total capacity of 512MB, comes in blue and will cost around $70;
