NW-S744K

The NW-S744K incorporated built-in speaker to the seventh-generation S Series 8 GB model. It maintained the x-app and PS3/TV focus of the family. Featuring 8 GB storage supporting MP3, WMA, AAC, and WAV playback plus video and photo, it includes the 240x320 TFT display, 42-hour battery, WM-PORT, Clear Audio, DSEE, Lyric Pita, x-app, and speaker.

The K version keeps that same cleaner S744 identity and wraps it in a more casual-use package. What matters here is not the bundle itself but what it says about the maturity of the platform underneath. Sony no longer needed to reinvent the line every year; it just needed to make a good one and let it branch.
