The Walkman A810 series is a portable media player designed by Sony. It was a flagship model in the Walkman digital player family. The model debuted in Asia in 2007, and then became available in North America. This series updates the previous Walkman A800 of the Walkman A Series, with the same hardware but different on-PC music management program.
Sony released 3 models, the NWZ-A815 (2 GB), NWZ-A816 (4 GB) and NWZ-A818 (8 GB). Some of the enhancements made include compatibility with Windows Media Player 11, and the infamous[clarification needed] Drag n' Drop feature, which allowed the user to transfer Music, Photo and Video files quickly, via windows explorer, (using ID-Tags for the song information i.e. album, artist etc.). Sony also removed compatibility with ATRAC which replaced the customers need for SonicStage, with Windows Media Player 11.
In March 2008, Sony launched its successor in United States, the A820, featuring wireless functions and with larger display and memory.[1]
