Page "Walkman" Paragraph 34

Some hardware changes include the exclusion of stick remote control and the usage of new connector for charging, accessories and data transferring.

Starting with the NW-S series, Walkmans feature Sony's new proprietary port called WM-PORT which is a USB 2. 0 compliant 22-pin connector.

Another notable hardware change is a color screen which can display album art.

These models also use new power management features which give the device a three-hour battery life after only three minutes of charging.
