The JVC XS-SR3, a new docking station from JVC can take either mini, nano, photo, video, classic and touch and has 2 2.5w cradle speakers with analog and digital external input. Its also claims that its the first iTheatre speaker system with built in Dolby decoder.
With its neat holding cradle you can swivel your iTouch to view movies or vertical for app use. Unfortunately and a big mistake in my opinion its not iPhone friendly for some reason. With the external input socket you can also use it for portable TVs, DVD players or gaming system.
Its available in both black and white for around $190
