The new S-series model has about the same displacement as an iPod Nano, but adds interesting new features like noise cancellation (no fancy headphones required), 30fps video playback and an automatic playlist generator that makes choices based on your listening habits.

It’ll be $150 for a 4GB model and $180 for an 8GB one, both having 40 hours of music playback (or 10 hours of video playback on a 2″ QVGA display.)

And if that’s too pricey, for $100 or $140, depending on storage size, you can grab one of the new E-series models instead, which lacks the thin form and fancy software of the Walkman-S; or the B-series, which has no video and only 1GB or space, but costs only $45.
