Unfortunately for owners of the sixth-generation iPod nano, most docking music systems seem to swallow the diminutive player whole, making it difficult, if not impossible, to control. Enter the Waldock ($60). This tiny speaker system is designed specifically for use with the touchscreen nano, and features a 40mm driver with a specially designed bass chamber for full sound, a top-mounted dock, and built-in prongs that allow it to plug directly into the wall, like a night light. With music. And a touch screen.
