The majority of iPod docks are usually designed for the home, but the TDK Sound Cube is one of the few that's actually portable.
The TDK Sound Cube looks like an extremely retrofied version of the Nintendo Game Cube -- only it's not a game console. This cubicle gadget has a pair of coaxial drivers that will deliver surround sound despite its miniature size. There's also an equalizer, digital data streaming for audio decoding and playback as well as USB and 3.5mm auxiliary ports to connect devices to. According to Amazon.com, you can even connect a guitar or microphone to it in case you want to bring out your inner rock star.
The TDK Sound Cube is portable and will supply you with just about everything you need in a sound system.
