In addition to the Walkman NW-A840 that we mentioned earlier today, Sony has presented another PMP - the S Series.

The Sony Walkman S Series will become available in 4 different colors - pink, green, orange, and grey - and so far there is no information about its price. There are 2 models available, the small one that only has 8GB of internal memory, or the better one with 32GB.

Other details include a FM radio tuner, and a 2-inch LCD monitor.
