Trusted Reviews have published a review of the Sony Walkman NWD-B105 MP3 player. ‘In an attempt to give the NWD-B105 the edge over the competition, it has an ace up its sleeve. While you can simply drag music tracks to it as if it were a USB thumb drive, this player also has a lightweight piece of software on it that can be run automatically when you plug it in. Called Auto Transfer, this scans commonly used music folders for compatible tracks (the NWD-B105 supports WMA and MP3 files) and transfers a selection to the device. It's simple, but beautifully so and means you can 'shuffle' your music without having to resort to a more heavyweight application such as Media Player or iTunes. Why Sony couldn't have done this years earlier is beyond me?’
