Walkman rocks with Android

Once the vanguard of mobile entertainment, the Sony Walkman is ready to make a comeback -- and Google is playing in the band, adding Android 4.0 to the new Walkman lineup.

Sony says the Android-powered music player will deliver a distortion-killing S-Master Digital Amplifier from Sony and a "richer, bolder, and louder presence." The E470 Series, seen here, has a 2-inch screen and is 7-millimeters thick.

Integrating the Sony Entertainment Network's cloud-based Music Unlimited Service, the new Walkman will give users access to more than 14 million songs. With a monthly subscription, Music Unlimited lets users transfer their music and ad-free radio channels to their Walkman to listen offline. The device supports drag-and-drop transfers of music, photos, videos, podcasts, and playlists from iTunes for Windows via Media Go software or Windows Media Player.
